There's shitloads if you do a quick google search. Are you looking for a specific instrument and genre?

Here's some classical guitar pieces

well, I kept searching for particular songs and I was having trouble finding free ones.

I was just wanting some for guitar so I could try to learn to sight read. I know how to sight read, but I haven't practiced enough to be able to read it as fast as I can play it like tabs.

I guess it would be better to do a song I'd never heard anyway.
