I loved that line. Mainly because I hate J.Lo with the passion of a thousand fiery nuns. And secondly, I thought it was meant to be a comment on how all types of music are blending now to become this big mess of sounds. There are no rock stars anymore. It's just pop stars. There are no bands like The Beatles, Tom Petty and the Heartbreakers, Dr Hook, or the Stones. It's just.... I'm not even sure what it is but I don't like it anymore than Jon does.

I'd also like to point out that the line does say "So keep your pseudo punk hip-hop J.Lo junk/Your digital downloads".... so, I don't think he's just taking a shot at hip hop, which by the way, doesn't include Eminem, but also, J.Lo (duh!), those stupid shitty punk bands (ahem - coughGoodCharolettecough) and Metallica (Napster anyone?).
