You can use winamp to create a wave file. I'm too lazy to tell you how right now, but it's easy to do.
As for piracy and napster, here's a rant:
I just found out my music is all over the thing. I have mixed feelings about that, but actually I don't much mind.
I tried it out, I traded rare live concert stuff for rare live concert stuff. I didn't care about CD tracks I could just buy, and actually it was pretty cool. (I also booted anyone trying to DL from me who had no collection or who's collection was not like mine, stuff you CAN'T buy, just fan stuff, ya know.)
I gave even that up on ethics.
We are at the frontier of something new, something big. Anyone who busted into mp3 format for promotion and such the past few years are somewhat pioneers of independent music. I'm proud to have been there. Napster made mp3 a dirty word. Too bad.
This technology made it possible to collaborate with people around the world, do amazing things, make your music available to anyone with a computer and some know-how. Amazing. Sad conclusion.
End of rant.
