It's "llama"
Little tip: Open up Winamp, and type this at the main window
<N><U><L><ESC><L><ESC><S><O><F><T>
Note that you don't actually type the <'s and the >'s - those just indicate separate key presses. So it's NULLSOFT with 2 esc's in there after the L's ('cause that'll Load a file, hence the L).
make sure you're using the default Winamp skin for it. I don't know if this still works - I haven't used Winamp in years. But it used to, and it was cute
Do the same thing to get it back.
As for mp3 playing, I gotta give mad props to Apple for iTunes. Apple's getting <b>everything</b> right these days. You should go buy an old iMac and use it. God. I used to hate Apple. Now I love them. Wow. Anyway, iTunes is amazing for mp3s. Multiple playlists at once, etc. It's great.
[edit - SHIT! Should be fixed now. ]
