Everyone keeps rambling how great this CD sounds, and how way ahead of it's time it is. Yeah, back in 1973. Now it sounds as silly and dated as most of the music from that era. So it has been a consistent seller and one of the top albums of all time. So has Michael Jackson's "Thriller" and the "Saturday Night Fever" soundtrack, but I don't see anyone rambling about how great those CD's are. There is nothing ground-breaking about this CD; it's just plain pseudo-intellectual fodder, designed to make the listener think he/she is really into something deep. DSM has been certified 15x platinum here in the U.S over the last 25 years. The Backstreet Boys debut album has been certified 11x platinum already. Does that mean these are great albums? No, it just means the American public has bad taste when it comes to buying albums.
