House lights synced-up to Skrillex? Yes please!

Sir Paul McCartney brought down the house last night at the 2012 Grammys, performing first a new Valentine's Day-themed number and then some Abbey Road-era classics alongside the likes of Bruce Springsteen and Dave Grohl.

Unfortunately, there are still people in this world who don't know the former Beatle, judging by some people's reaction on Twitter.

Ohhhhh boy, not gonna go there.

Ugh, G-flat major? WHY NOT JUST MAKE EVERYTHING IN THE KEY OF C MAJOR? PLEEEEEASE?

That icy landscape looks like it's too slippery to play on - she's obviously having trouble walking normally.

In all fairness, you don't go into metal to get rich and famous. You go into metal because it's awesome. If you want fame, you get a stylist and sing mid-tempo love songs. I'm just sayin'.
