This just came up on the orb list.  Here's more or less what I had to say. 

Record stores certainly don't like to use the B word, so the usually call them "white labels.  The definitely aren't legitimate, since most of the time there's no chance in hell they could afford to license the lengthy samples, or in some cases the couldn't get permission to use them at all.  Basically the fact that they are using the samples without the artist's permission makes it a bootleg by definition.  These wouldn't be straight up bootlegs, but are certainly bootleg remixes.  At the risk of sounding pedantic I included the definition.

boot·leg
2.  To produce, distribute, or sell without permission or illegally: a clandestine outfit that bootlegs compact discs and tapes.
