I've always used aimp2, but my library broke file path metadata and the fixup tool fails to relocate them. I've looked at FOSS and free alternatives, and am not really, fully satisfied with any of them.
IIRC, I found none of them sufficient. Strawberry, Clementine, Audacious, MusicBee; all have dissatisfactory UI / UI structure for me. Foobar is way too minimal. From my exploration, MusicBee was the most reasonable, acceptable for me. The customizable tab setup is a confusing mess too, but otherwise… I've been using that for a while.
At some point I started implementing my own music player, making use of the BASS library like aimp2 does. But not much has come of that [yet?].
Maybe I can recover my aimp2 metadata, and will switch back to that.
