As Manipulator says, Music House, like all the other plate cutting places aren't labels, so I guess its a tricky one really - for e.g. I've got copies of Dope Pt2 on both Music House and JTS dubplates but would you really want to list them? And is there much value of doing so? Discogs tends to have dubplate/acetate tracks, where listed, as simply 'Not On Label'. Admittedly, the only situation where I've listed acetates/dubplates in that situation are where the track hasn't been released or its significant enough to warrant an entry - I ummed and arred for quite a while over listing my plate of Dextrous - Moonlight, and only did so in the end because it simply wasn't listed anywhere else on discogs (as I don't believe the 'Rites of Passage' CD is listed). Interested to see what Haste/Logic consider for here?
