That's the reason I'm still using Winamp. Its aged surprisingly well and it has more features than a lot of modern media players.

It really whips the llama's ass.

There's also http://aimp2.us/, which, AFAIR, in some respects whips Winamp's ass. Sadly nothing comparable to either on Linux.

Winamp 2 or 5?

Version 5 kinda sucks.

Maybe its because I don't know what I'm missing, but I didn't start using Winamp until version 5, and I think its great. Sure it has a lot of unnecessary or even broken features (looking at you audio converter), but those are easy to ignore and you can even remove some of them.

This is one of the (few?) things that iTunes gets right. Though it's a little hidden, the entire program can be minimized into a small floating album cover.

And if that's not small enough, you can minimize it altogether and just get updates and controls via Notification Center.

Foobar2k on Windows and Deadbeef on Linux seems to do much the same job of playing music while staying minimal.

Sorry, but I see nothing minimal in their screenshots [0]. Same iTunes for my taste. I do believe the performance footprint is minimal, but that't not the first aspect for an everyday app.

Vox on MacOS does this by default. Very simple/fast/small music player.
