With the new CD, I've decided to drop the Share-Alike clause from my license. My music is now all available as Creative Commons Attribution. This means you can use my music for anything, as long as you give credit for it. [More Info]
I've been debating on this one for awhile. Obviously, I prefer that derivative works are also licensed as Creative Commons, but pretty much every day I'm waiving that provision for someone, so they can use it in a context that doesn't play well with CC (YouTube, movies, ads, etc). Now there's no ambiguity, and you can hack apart my music at will, as long as you give me credit.
This applies to "Breadcrumbs" and all of my other albums and songs, including the instrumental mixes. Enjoy!
