The 2010 Oscars: Best Song Used To Mean Best Performance, Man!

It's no wonder that the Academy has decided not to include performances of the nominees for best original song—seeing Princess and the Frog theme song "Almost There" isn't exactly guaranteed to raise the roof. Neither would Nine's "Take It All," to be honest (Sorry Marion, Daniel Day, and co.) This wasn't always so; there have been some pretty amazing original song nominees who really nailed it on Oscar night. Check our audiovisual rundown after the bump.

Three 6 Mafia's detailed set design and dance party lighting transformed this 2006 Oscar winner into a live action music video that's made for the stage. Not to mention the showcase of Taraji P. Henson's pre-Button pipes; girl can sing as well as she wears old-age prosthetics.

Okay, okay, Aerosmith's sap-tastic 90s hit is hardly a rock gem, but you gotta admit, Stephen Tyler looks cooler dancing with his scarf-y mic stand than you probably did  slow dancing to the same song at your junior prom.

Multiple divas on one stage can have disastrous results (think VH1's high-maintenance convention, "VH1 Divas"), but Jennifer Hudson, Anika Noni Rose and Beyoncé play off each other in this 2007 Dreamgirls medley with a kind of grace that Mariah Carey and Whitney Houston never managed to scrounge up.

No one can forget Elliot Smith's 1998 "Miss Misery" performance, especially in the wake of his suicide. Smith's solo performance lost out to Celine Dion's "My Heart Will Go On," but no amount of dramatic chest-thumping can hide the fact that Dion's adult contemporary sobfest doesn't hold a candle to Smith's captivating acoustic ballad.

Sure, Glen Hansard and Marketa Irglova are outrageous musicians, but their real talent lies in playing the 3,500 seater Kodak Theater the same way they would a tiny bar or a Dublin street corner. They come off as completely authentic and genuine, a surprise show-of-a-lifetime for a crowd that's really only there for the movies.
