Miss me with the "digital" and downloading excuse. Today's pop stars - like Katy - don't sell albums like they did a mere 8-10 years ago (when piracy was still an issue) because they simply aren't as good. Their music is cheesy and generic, and the GP doesn't trust their whole album to be worth the whole $10, so they just download the nonsense being pushed on listen to it on YouTube. Adele proved people will still buy albums if you can convince them you're worth it. Clowns like Katy and Rihanna don't, so all they can move are singles with an embarrassing album sales ratio comparison.
