I like the ability to buy individual songs versus having to buy the album. That wasn't the case when I was younger because my tastes were much more limited, so buying an album was no big deal. Now, my enjoyment of music has greatly expanded to genres that I would have been turned off to years ago. I may like one song of a particular artist and not really care for anything else that artist does. I can now buy that individual song, whereas decades ago I couldn't. If I had to buy every album today my music collection would be greatly diminished.
