so now I am in the ipod world , and have a subscription to one of these monthly download services , I was wondering about stategies for selecting songs...On the one hand its great to be able to download a wide range of tracks from bands whose music you are not sure about without the expence of an entire cd price, but doesnt one tend to preview the individual tracks prior to purchasing them , so that in a way you end up taking the tracks that have an initial appeal only.?? Or do you read reviews which talk about the better tracks off a disc? What do you people do?
