^Two awesome sites::
http://dig.ccmixter.org/music_for_film_and_video - they have
other types of music too. The music is completely free to use
for anything, so if you make videos and worry about copyright
and stuff, this will work for you.
And....
http://www.freesound.org/ - where you can use and share SOUND
CLIPS for free, no copyright, none of that stuff.
This one is exciting to me because I have ALL THIS MUSIC but I
don't wanna perform any of it, or mix songs and crap, but I want
my stupid talent to be useful for something. So at least I can
upload the little musical bits and maybe someone can mix it into
their songs or whatever.
I finally found a reason to bother splitting my music up into
clips. I could never do it for myself - the editing process is
just too boring for me. Same reason I can't write music, just
make it. "writing down" music is boring.^
