I propose Rockipedia be added to the database whitelist. Rockipedia is a website with norwegian music (not just rock) it has releases and clips for listening (good for disambiguation) and advanced relationships like information

example: http://www.rockipedia.no/utgivelser/meeting_in_the_mountain_-_a_meeting_betw-6259/

they have information on
releases http://www.rockipedia.no/utgivelser/
http://www.rockipedia.no/utgivelser/juba_juba-20390/
releases can be both our "release group" and our "release" this will have to be made on a case by case edit, generally it's considered another release if the tracklist changes.
