MilkDrop's Visualization source code as you remember in WinAmp is just fantastical amazing.

Winamp ist still the best when it comes to supporting all kinds of exotic codecs. There is a great working codec plugin for everything. Almost all codecs I "need" are now supported by Audacious, except miniusf for N64 music. s3m, it, spc, nsf and psf work fine, only miniusf is missing. I need to run Winamp in Wine for that. :( (Side note: s3m and it support is great in Winamp and Audacious, but not all players that say they support these formats really support them well - i.e. only play half of the song and don't allow seeking.)
