So music is now times a matter of taste. What one person likes, I like the other not and vice versa. But I agree with my prescribing broadly. Mostly a handful of useful, good titles are on top of the double CD's, the rest of the songs you skip prefer directly.
But there are alternatives: My personal summer - favorites this year: "We Love Summer 2012" Comparing just look at the selection of the various "Summer Double Hit CD's" and then meet your decision ;-)
