Winamp was pretty cool. When I switched to Linux, many years ago, I wanted to have winamp too. I think I used bmp for a while until it died; before that xmms but that one also sort of died.

Meanwhile some other GUI showed up, I forgot the name. I kind of gave up on winamp, mostly because my use cases shifted. I went to mplayer, then mpv, and now I am too used to using mpv for literally anything related to audio and video (which in turn uses ffmpeg of course). I kind of built a commandline helper variant that just plays anything I have local - audio, video. I could probably go and find a nice UI again, and that may have advantages such as simply scrolling through the list or setting ad-hoc favourites, but I don't quite need it anymore; I am faster with the keyboard too, so my use cases changed. To play all audio from Hans Zimmer, for instance, I may type "rsong Zimm" or something like that. (I also alias a lot so I may just type "zimmer" instead, but most of the time if I use it I just have it default to random selection as I don't care what is played normally.)
