How about for a URL that satisfies the requirements of an MP3 WOAF
field?  This is a lot like Greg's http://www.GregLondon.com/cc/by, but
isn't exactly the same.  Or is it?  How are other people approaching
the verification URL for a song file?  Do you have one page per song?
How do you set up personal identifiers in the page which are capable
of being used to verify that it really was you who made this license
grant?

Per http://wiki.creativecommons.org/MP3 a WOAF field is "WOAF
(Official audio file webpage) should include the URL where the work
metadata, including verification information, may be found."
