If that's the case, then who is buying this music? Isn't everyone's libraries already saturated with the songs they enjoy?
From that I extrapolated that you can make a lot of money if not more money from a bunch of micro purchases.
I don't own any MJ music, but I like at least 5 songs enough to buy them. (Only reason I didn't is lazyness in getting around to clean up my music collection and having it all on my computer etc.)
