Sony fanboy S.B. sends us this link to Onion's AV Club list of the 15 best uses of pop songs in movies. It's a pretty solid list--including Boogie Nights, Almost Famous, Goodfellas, and more.
We can all make our case for overlooked scenes, of course. I'd agree with S.B. and say that Aimee Mann's "One is the loneliest number" from the opening of Magnolia should make the list. You make think otherwise.
