I had the misfortune of using Windows Media Player before. But, I did find something kind of neat.. an advanced tag editor.
(note my sisters horribly large Comic Sans MS font in the titlebar)
Now, I propose to you three things:
1) is there a plugin like this for winamp.
2) if so, can you set the mood of the song, and then play your "mood" songs?
3) if it isn't already included in winamp, whyfor not?
Something to think about.
also, while I think about it, is there any good nullsoft signal processing studio stackers about? i'm looking for a tweak that'll boost my bass too.
