Musicians Joshua Ellis and Big Friendly Corporation have implemented a new technology called BitPass to sell their Creative Commons-licensed content via micropayment.

Joshua has offered his songs under an Attribution-Noncommercial-ShareAlike license. If you buy a song for 50 cents, or the entire album for $3.50, you’re then free to copy, distribute, and make derivative works — as long as you give Joshua attribution, don’t make commercial uses, and release all derivative works under an Attribution-Noncommercial-ShareAlike license. Joshua says he’s sold over $100 of content within a few days.

Anyone interested in mixing these songs, or putting them into your student film?
