If you think about it, there are more people buying/downloading music today than the 60/70's, of course the record sales will be high. As for Katy Perry and Dustin Beaver, they both have talent but nothing compared to Elvis/Beatles etc. Trouble is that all the great songwriters are now dead or soon will be, the question is, who will take their place? In twenty years time the Beavers of this world will be long forgotten where Lennon\Elvis will still be remembered.
