I only use songs that are related to what I am doing on guitar and so I don't ever need the whole album and actually if I was downloading them to listen to I wouldn't download a whole album without hearing it since I can think of only a few albums I've ever listened to that every song on it I liked, maybe less than two, unless you are talking a greatest hits album.
To be honest most of what I download I've already owned and purchased at one time or another on casssette, 8track, vinyl or CD. How many times do I need to give them their money, once is more than enough.

It's a long way to the top if you want to rock n roll!
