If you only like certain songs by an artist, then buying the compilation is a good idea in my opinion. I own Guns N Roses, Bruce Springsteen, and Bonnie Tyler's compilation sets, and I listen to them on a regular basis. In 2000/01 the only Meat Loaf album I ever listened to was "The Very Best", and when that got damaged I bought another copy.
Does anyone think the compilation sets are good value for money?
