Hey everybody. I've recently found out about this site that is perfect for collaboration called Notethrower. It seems really new because it's just a beta but apparently you can upload your music, ask for instruments that you want in the song, and someone can download the song to collaborate. So say if I wanted drums in my song someone could download my song and make drums for it. It seems really safe to because you can license songs/sell them through paypal. I'm waiting for it to take off because it should be sweet with more material to work with.
This is actually a really interesting idea.

I could see problems arising with it though.
Seems pretty cool. Probably check it out later when I'm not so tired.
