My track Cuckoo with the lovely vocals of Lisa DeBenedictis is reused in the open source film Stray Cinema:

Another fine example that thanks to the Internet, remixing is as alive as it used to be in the early days of hiphop. Reason? Because a less restrictive copyright which I am using, Creative Commons, opens up these new possibilities. Art = recycling = remixing.

Expand your soul!
