Description of Issue

I’m new to Roon but a long time user of MediaMonkey. I’ve noticed there is a significant discrepancy in the statistics reported by the products. Example: Roon lists 3368 Artists, 8809 Albums, 144,539 Tracks - MediaMonkey Lists 7300 Artists, 10,599 Albums, 145,535 Tracks They use the same source info. Any ideas as to why these differences exist between the products?

Are you looking at the main home screen to make this distinction? Check to see if Roon skipped importing in some albums due to some issues. You can do this in the library section of settings. Also check for unidentified albums. You can do this in the albums section and use focus to look for unidentified tracks. You will need to match these to known versions in Roons metadata database.

Thanks for the tip. I have 26 audio files that didn’t import. They were flagged as corrupt files. I checked inn MediaMonkey and they are not there either. Looking at the properties of the files both Sample & Bit Rate are zero. Makes sense. Not enough there to explain the descrepany. :frowning:

Roon will also hide duplicate albums by default. You may have different versions (e.g. Hi-res and CD, or Stereo and Surround) of the same release, and Roon will group these under the Versions tab on the album page.

You can turn off this setting on the Settings > General page, then Roon will count all versions separately.

What kind of albums do you have? (Classical, jazz, pop?) How many box sets do you have? If many, how do you have them organised in MM and in roon? How are multiple artist albums represented in MM and in roon (MM may count each of them as a separate artist while roon might treat them as a single artist like a group; Simon and Garfunkle may be two artists in MM and one in roon, for example). You say you are a recent user of roon so that probably means all your albums have been organised by roon’s own metadata while I would imagine you did a lot of the metadata work in Media Monkey and that surely lead to discrepancies. Are there albums in MM that are not in roon?

I turned off that setting but no change in the Album, Track counts.

Thanks I’ll try that.

Any thoughts on the Tracks discrepancy?

Also is there a way to get a list of Albums out of Roon? I could then do some quick lookups against what I have in MM to find the discrepancies.

You can export the contents of your library to an Excel spreadsheet

Thanks Geoff. I poked around on that link but can’t figure out how to export everything to excel. Can that be done?

Go to the Album browser - select all your Albums (Ctrl-A on a windows machine), click the “3 dots” menu at the top of the screen and choose Export.

Well that was easy!

Thank you

I have over 50 genre’s of music. I don’t have a count of the box sets but it’s well north of 100. Some box sets have multiple artist represented. I don’t have any group albums that meet your Simon & Garfunkle example. I have edited a lot of the metadata in MM for consistency. Even music that comes tagged I check for consistency. Been doing it for more than 20 years so it’s pretty accurate though I’m sure there are errors. I’m trying to work with the data exports from Roon & MM to find some of the things that have been suggested here. I’ll update when I make some progress. Thanks for the suggestions!

If you have manually groomed metadata on boxes , be aware of …

  1. if you file structure is say CD1 - Beethoven x, CD2 - Brahms y
    Roon will see that as 2 albums and split them then probably struggle to ID them

If the structure is a bare CD1, CD2 … CDx then Roon will try to group them BUT see 2)

  1. if a box has the Album tag set to a different value per disc it will confuse Roon .

To properly import a box , set folder names to CD1 etc and all [album] tags set to the same value’ eg Alfred Brendel : Complete Philips Recordings . Roon will group them and probably ID

Splitting boxes into “pseudo albums” often fails

With a 100+ boxes that may well account for some of the differences

There is a Knowledge Base article on this subject

I edit the boxsets based on how they’re organized. I also eliminate subdirectories by renumbering the tracks on each CD. Disc1 Track 01 becomes 101, 02 becomes 102… In your example “Alfred Brendel : Complete Philips Recordings” the album names are all the same. However with Woody Guthrie My Dusty Road set each CD has a unique name; Woody’s Greatest Hits; Woody’s Roots; Woody The Agitator; Woody, Cisco and Sonny. Another example of that is the John Coltrane Prestige Sessions where I’ve tagged the tracks with the actual album names. These appear as seperate albums in both MM & Roon.

Do you have a link to the KB article?

Does Roon recognize the 101 102 format ?

I use that format to sort into Folders but then I renumber back to 1, 2 etc

I use Tag & Rename its great little tool

If the album name is the same throughout , did Roon bulk it as a 114 CD set… It may take manual ID though depending on track time matches I found.

PS in terms of album counts , do you have many where you have 2 or 3 versions , Roon will bulk those by default then show as 1 album but 3 versions etc so affecting the album count !!

Not on the main homepage it shows the full count only on album or track view does the show hidden albums or tracks come into play.

You can easily find unidentified albums via the album browers, choose focus and in the drop down you can find one that says identified, click on it to add it then invert the focus by clicking on the +and it will show one’s Roons failes to identified.

You learn something new every day, I thought the home page showed albums including versions

Not unless you change the default in Settings > General to show hidden albums and tracks…

It does it include all versions all the time in the count, only the albums view count changes with those settings. This is why users often get confused over the differences between the two counts.
