I see Happy Records are tagging their music with "Ring Musik" as the performer instead of the original orchestra or band name. This is a very unfortunate practice, and I've noticed it with APM too.
Though in most cases one can get the performer details from Discogs. But I agree it's a drag.
I can kind of see why they do this, but it doesn't help when trying to cross reference tracks if the only details are of the composer/artist rather than the orchestra/band which the track is performed by. Some are easy to work out, obviously, whereas others can be quite nebulous, particularly if they're a pseudonym or alias of some kind. We do get a little bit of help thanks to the, 'Composers & Artists', section on here, but even so, there's a fair number that can often come up blank as to who the performers of pieces are.
