Tunefeed is a music sharing Widget created by Faces.com that can be easily placed in blogs and personal websites, with a more detailed function to create your own music playback and sharing list. I don't know how foreigners control music copyright issues, but there seems to be some mechanism in place. The Widget, which also has tag and comment features, acts like a mini music blog, and is currently in a closed beta, so you can sign up for an email queue.
