I've been composing and working on http://OurMusicBox.com for some time.
Instead of setting a price, I have decided to offer my music free. I have a few thousand tracks free under the creative commons license. They are royalty free too. Just credit me with an active link and perhaps buy me a cuppa on the way out :)
909 Music is a Royalty Free Music Library and Social Platform for musicians with a massive library of several different styles of music servicing a wide range of productions such as: Films, TV Commercials, Jingles, Video Games, Corporate Videos, YouTube Videos, 3D Animations, On-Hold Music, Music for Hotels, etc.
If you've ever used a popular song on your YouTube video that was copyrighted, you might have received a take-down notice, or your video might have sudenly disappeared from YouTube's page. You want to use music legally, it enhances your video, and now you can. YouTube announced the launch of the Youtube Audio Library, allowing users to edit royalty free music into their videos - free of charge.
