Foobar2000 was the hardest app to replace when I switched from Windows to Linux. I finally settled with Clementine which is great too, but that was basically the end for my music collection, organization and rating hobby. I had even built my own replacement to Last.fm/Audioscrobbler backed with a local database as I wasn't happy with their feature sets, and I meticulously kept all tracks uniquely identifiable with full tagging to derive some data of my listening habits.
That all basically ended -- instead of being an active process and participating in vibrant communities my music listening changed to just that, listening. The eventual switch to Spotify was much less dramatic for me. Sure it was replaced with something else to tinker on, but some of my fondest computing memories are thanks to foobar2000.
Same thing with a move to Mac over a decade ago. I still feel icky that most of the stuff I've listened to this past decade is archived on such a closed platform, and once in a while it itches enough that I use a downloader of sorts to try and at least archive them somewhere. But the curated library of tags, endless dynamic playlist generation, and aimless wandering through torrents and articles are all but gone. And along with it a certain aspect of the love for music.
I had a similar experience. I tried every linux music player I could find, nothing came close to foobar. I also settled on Clementine which I still use, but I stopped collecting and organizing music locally as a result of the switch. I even spent some time coding a new music player before deciding to just settle on clementine.
