I've been looking at Creative Commons licensed music for use with my videos. There are a number of licenses, but typically they allow sharing and use in non-commercial products.
There is a lot of web sites dedicated to free music, and I've found some music by Manolo Camp that I really like. Here's two web sites with his music for download:
Morning Coffee or Ships in the fog. I'm already picturing some video that I can shoot for that second track. Anyway, hope you like it.
Update 11/12/10: I've published my first video using Manolo Camp's music "Medieval". I think the music really adds polish to the video.
