The links to myspace are using owl:sameAs. The mo:myspace property
points to a document (the myspace page), whereas we're asserting
sameAs links between the same artists in Musicbrainz and Myspace. Try
something like:

PREFIX mo: <http://purl.org/ontology/mo/>
SELECT ?myspace WHERE {
 ?x a mo:MusicArtist;
   owl:sameAs ?myspace.
FILTER ( REGEX(str(?myspace), "^http://dbtune.org") )
}
LIMIT 10

Cheers!
