First of all, it respects albums. Other players like VLC and Fubar2000 would order the songs alphabetically; it's annoying. Also in the "artist" list "The Beatles" comes right after "Beasty Boys" the way God intended.
Second it has an "always on top" feature so you can easily control it while gaming.
Winamp was made for people who listen to music the way I do. You know, old people.
AIMP on Windows (and probably Wine). Has good converter and tag editor as a bonus. You can try v2 or v3, they are pretty different. Both support Last.fm scrobbling if it's still relevant. The android app is nice too but I haven't used it that much. It kept my evergrowing library nicely structurized, mostly folder-based, with a little effort. It's russian, but I haven't noticed it doing anything funny, and it's probably too niche since most people use streaming nowadays.
Quck search suggests sorting by album will also sort by track number in it. Also I found 4 year old feature request for VLC Android for sorting by track number that was added 4 years ago.
