Three things about this:

 * Their XSPF is not valid, can you mail them?
   (I saw <itunesurl> tags outside extension tags
   somehwhereb else before!?)
   Offering to add them to our application
   section could be a good point :-)

 * Shouldn't their encrypted <location>s really
   be <identifier>s instead? That would other
   clients keep from actually trying to read them
   since them don't know what to do with that kind
   of identifier.

 * Their encryption has at least one big weakness:
   Files share quite long prefixes. While that is also
   is waste of space it reveals that they (probably)
   just encoded  folder-filename like strings. Together
   with the track information from the flash player
   it should be possible to reverse their encryption. :-)
