VGMDb should be release-URL, their entries are the same as Discogs and NGS releases. LyricWiki aren't consistent when it comes to creating separate pages or not, so sometimes there could be multiple links, but I think their pages are closer to release groups than releases. I'd currently suggest release-URL for IMDb samples and recording studio, since we're currently using artist-release for "samples from artist" and "recorded". There's only one album-URL score relationship, but I'd probably treat it the same as lyrics. For streaming music, I think that's also similar to lyrics in that it's just a set of tracks and not specific to a particular release (event), so I'd say release group for that too. --Nikki 19:17, 19 November 2010 (UTC)
