This compilation is a real mixed bag - there's some decent stuff on here, but also some questionable sound quality, at least one track that isn't a 12" mix and at least three that are edited!
SOUND QUALITY - nothing awful: this certainly isn't over loud, but it sounds like some tracks have been sourced from vinyl and some sound like they have additional reverb/exciter added to them. Some tracks just don't sound quite right to me.
NOT THE 12" MIX: "Easy Lover" by Philip Bailey and Phil Collins. Is this the LP version? It's not the 12".
EDITED MIXES: "Heart and Soul" (Remix) by T'Pau. This is either edited by about 1min or is the LP version. "Don't Turn Around" (12" Mix) by Aswad. This has around 1min 10secs shaved off it. "Don't Talk To Me About Love" (Extended Version) by Altered Images has around 1min 30secs removed. "Girl You Know It's True" (Super Club Mix) by Milli Vanilli appears to be mistitled or missing 1 or 2 minutes depending on which Super Club Mix you have.
