Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Much less than what I expected

I bought this CD after reading praise reviews at PerfectBeat.com and sampling the songs figuring getting this compilation will eliminate the need to buy certain singles. Some great songs included here like hard-to-find Deborah Cox song from Aida, Monica's "Get It Off," Benni Benassi's "Illusion," LMC, Narcotic Thrust, "Summer Jam," etc. However, many songs have been butchered by jumping to vocal parts and skipping the instrumentals (which are in the mixes for a reason, othewise radio versions would be just sufficient). The transitions seem rushed. I totally agree with some other reviewers that transitions are not smooth and especially that the sound quality is very very poor. For the lack of a technical term, the sound is just flat, as if the disc is recorded in mono.I would not stay long on a dancefloor if this mix was playing. I am so glad I bought this CD used.
