Totally understood. I just never know what “did you listen to different stuff” means for me, because I rarely listen to the same stuff very often (except for like Blue, Eat a Peach or Paranoid which will hit heavy rotation for a week once in a while). Vive la différence!
I guess I didn’t phrase it well. I didn’t mean different in genre etc., just something else that you had not listened to previously.
I don’t expect SDL to change things around for no reason, because I am guessing the way it works is that it assigns a score to every album based on its listening history, and then it downloads the top X album scores that fit into the designated SDL storage amount.
So if my subsequent listening (after the download is done) does not significantly affect the scores, then I don’t expect a change of downloads. But if I do listen to something new often enough that its score becomes higher than the least-score album that was previously downloaded, then I think SDL should download this album and remove the previous least-score album.
Hence what I meant to ask was if your listening scores changed after the initial download
Got it. To clarify why I was puzzled… Many many of the albums I downloaded were ones that I have not listened to in years, or ones where I know never listened to them (my brother in law ripped some mid-70s Brazilian rock on my machine). So that’s why I was puzzled. It’s a good mix of things I listen to and things I do not. I have mine set to balanced, so 15GB gets 100’s of albums and I see a lot of diversity. It’s been fun to explore stuff I’d forgotten about - I’m one of the folks who is sad that Discover is now buried deep on the home page vs in the left nav, so this has a functional similarity for me!
I assigned 30 GB and do CD downloads, so about 100 albums I guess. I tend to listen to albums repeatedly a lot during working my way through my interests, so I don’t accumulate lots of different stuff with just one or very few plays.
I guess that made it easy for SDL to pick the most important downloads, and in addition to that it choose some that gave me the same surprise feeling as you, happy to be remembered of the odd half forgotten gem.
I guess we’ll see over time how it behaves with replacements. I’m sure there’s lots of room to tweak score gathering, but I don’t think it should try to be a rediscovery algorithm - that’s a neat thing to have but I think it should be in a different place. SDL should just try to have downloaded what I most likely need offline right now in case I don’t have a connection. So my most frequent plays / most favorite albums, the most recent plays, and any new imports should have a high score. If there is still free storage after that, I’m open to being surprised

Until, like me, you acquire the entire Geometric Lullaby back catalogue and decide to ingest it in Roon, and end up in Vaporwave and Phonk nirwana on your next roadtrip! 
I definitely agree with this - it’s hard to understand why it thinks that I’ll suddenly start listening to old albums I have never even played on Roon (to the best of my memory).
Well, it should not be too hard to put a limitation on that
Did you have enough assigned space? If yes, then why not? It may have chosen by genre or artist links or something.
In my case, it clearly filled the space with the frequent stuff and then the leftovers with rare stuff. That’s fine for me
Sure, but that’s a completely different function. Stuff I’m most likely to listen to will mainly be a mix of newly added, recently listened to and favourites…I’m all for a musical magical mystery tour, but I understood this function to essentially be clever caching, which is something different. I gave it 40GB and it downloaded 120 or so albums (I have 321 favourites). Just my point of view by way of EA feedback…maybe others want it to behave differently.
Edit: It’s possible my behaviour is confusing it a little. I moved to Qobuz in October which reset many of my play counts on streamed content, as well as resetting the added date. I’ve also manually tagged stuff I haven’t heard in a while and want to remind myself of, so I have been working through that…although since it’s mainly streamed that seems less likely to be relevant.
I agree that it should be a clever cache, but my point is that if there is still empty storage space after cleverly caching all that can reasonably be cleverly cached, then it should fill the rest of the storage anyway with guesses or far-fetched stuff, rather than leaving it empty.
That’s what it looked what it was doing for me and based on your info I couldn’t tell if it’s like this for you or different, hence my questions
I actually prefer it filling in with the tail end of my collection. It’s good to have something other than the favourites if you are offline for a while, which is the reason for the large offline cache in the first place.
Exactly, as long as it isn’t leaving out favorites / frequent albums / new albums in favor of the tail end, all seems to be fine IMO
Understood…but it is doing precisely that. It’s not something I’m going to get exercised about as I don’t see me making much use of it…just giving my feedback

My observations can be influenced by bugs stopping download. I mean that I my download process might be not finished yet but interrupted due to some bug.
Originally on build 222 smart downloads stopped for me after ~10 albums.
Some time after build 223 (although not immediately) installation resumed and SDL downloaded around 115 albums. Then it stopped, I added 10 more GB of storage for SDL but nothing more happened.
As a result I currently have around ~110 SDL albums and 75 downloaded independently or moved to my downloads. But the whole Roon library contains around 600 local albums.
And the selection in ARC is surprising. As in your cases, it contains significant number of albums not listened to for a long time.
Unfortunately MANY of the frequently used albums are missing.

It is designed to rotate content. The interval of rotation depends on how much “valuable” content you don’t have already on your phone. Things like listening to stuff, favoriting stuff, adding stuff all impact an item’s ranking.
The idea is that SDL are an ever rotating chef’s menu of your own music you’re likely to enjoy. If you really enjoy it, “saving” an item ensures it won’t get scooped up and deleted in the next rotation.
Hope this helps clarify!
Thanks for testing

Thanks for clarifying - that makes more sense now as to why it’s working the way it is.
ARC still gets itself into a state when in edge connectivity and can’t see the server for a while.
The initial Chuck Prophet song was stuck in that vibration mode with no audio.
In the second song the audio was actually playing all the time despite hitting play and pause repeatedly.
I had to kill the app, start it and manually switch to offline before it would play again.
Once it’s decided it can’t contact the server it starts behaving oddly quite often, it won’t go offline without having the instance killed and a restart.
Hi @Suedkiez ! Thanks for the report. The fix is going to be present in the next release.

Michael, can I ask if this is about ‘new’ favourites, as opposed to existing favourites? It look like my favourite albums are under-represented in SDL. Imo the opposite should be the case.
There around 3700 albums in my (all local) library, of which around 90 favourites, so around 2.5%. I would have thought that these will be substantially oversampled in picking SDL candidates, but there is - currently - exactly 1 favourite amongst the 366 SDLs, or 0.3%.
There are 3 further favourites, amongst my 71 permanent / manual downloads, so at least 80 of my favourites are still ready for the (SDL) taking in a pool of ca 3300 non-downloaded albums.
I understand that new favourites are absolute surefire candidates. But surely existing favorites should also be over- rather than under-represented. Especially considering that in an established local library, most favourites will likely have been marked as such already, with ongoing library changes and additions probably only constituting and generating a slow evolution in the overall picture.
Hey, all favorites should be considered, not just new ones. Those numbers feel like they’re within the bounds of the current iteration of the algorithm. We will definitely be seasoning to taste as time goes on. Thanks for your feedback.
