a) said when an album was last played. I know I can sort tracks by last played, but tend to browse by album where i can’t see that. Date in the same area as ‘Released’, ‘Added’ etc maybe that shows the last date any track on the album was played?
b) lets me search for things I’ve only played once (or twice maybe) - played less than x, but not 0 times. Again by album ideally. I have loads of stuff I’ll probably never play (ancient stuff I’ve had for years, or things my other half bought, that I’m only bothered about if I’m looking for something specific), but I’d like to find the things I bought in the last few years, played once or twice, then forgot about.
You can also be more granular, and have it spit out the unplayed stuff that you added in the period you’re interested in (or whichever other available criteria you’re interested in, say unplayed albums recorded in the 1960’s added in the last 6 months).
It isn’t Radio, but you can then hit shuffle on only the unplayed stuff
Go into focus, pile criteria on… part of the under-the-bonnet beauty in Roon is that it allows you to do stuff like this, and it’s super-responsive at it.
(I added a screenshot of the type of filtering I was describing to my original post)
Go to focus. Select played in “all time” then select the result filter to make it a negative which will give you all tracks never played. Then select the genre, date range etc.
