Addictions Vols. 1 & 2 are great on their own, but they are designed to be stand-alone projects, not a representation of the original recordings. Robert went back into the studio and re-mixed (and even re-sang) many of the tracks to his liking. If you get the original LPs (or the new "Collector's Edition" CDs that are now available on Amazon), many of the songs sound quite different.
