But I have "POP!-20 Hits" already and think that was a better representation of why Erasure was so great. Btw, with this new collection having 3 covers of ABBA songs, why doesn't it have their great cover of Blondie's "Heart of Glass"?So anyway, should you buy this or POP!? I have the solution: backtrack and buy all their cd's in order and experience Erasure to its fullest. Most of their cd's have too many wonderful undiscovered/unheard gems in them.
