Well, I have to say that Harmonoid is the best one I’ve found, it has a ton of cool features, it works and it allows you to be able to see your collection by album and it doesn’t use Electron. Right now its development has stalled a bit but it’s still pretty much in good shape, though.
Sadly still no alternative that comes even close to MusicBee.
I need one that does it all. Extremely large library, complete and complex searching, filtering, changing which columns are displayed/how, complete tags editing and display including less common ones, and the ability to add custom library tags (such as tags for grouping purposes, which I use extensively on top of Genre and Comment). Also need gapless play, ability to add fade in/out and control the length of that fade either when skipping or between all tracks, ability to edit the start/end of some tracks, etc. And good tools for auto-tagging, automatically fetching album art, easy re-organizing like MusicBee which allows you to auto-rename and move selected files along customizable rules, etc etc etc. MusicBee has tons of really good tools and 90% of them are basically required for how I organize and add to my library. And a clean and configurable UI where I can decide what I want to see and where it is, wavebar, visualizers, good controls and a nice auto-DJ, etc etc.
Works really well with Wine now, but still there’s some annoying things like it not being detected as a media source, and not being recognized by the normal media buttons/widgets. Also recurring audio problems (need to refresh Pipewire or switch the sink) which have gotten better but still not quite there.
God audio stuff on linux still has a long way to go.
I’m in the same boat; longtime MusicBee user on Windows, and it’s one of the few things I haven’t found a “good enough” replacement for on Linux.
I thought I was the only person who used MusicBee. Crazy to hear it not only brought up, but recommended here. I started using it years ago on a whim after a really basic “try these windows music players!” listicle
