20 Songs You Gotta Download Before Grammy Night

The tunes you need to get before 2013's biggest music awards show

For an award named after the old-school gramophone, this year's Grammys seem surprisingly relevant in the digital age. 

There's honest-to-goodness variety in several categories, plus a nice balance of proven brands—some Coldplay, a little Taylor Swift and Rihanna—and relative newcomers who pose actual challenges to each other (hello to fun. and Frank Ocean). For our money, these 20 primo tracks amount to a nice primer for the festivities, which go down in L.A. (and on CBS) on Sunday. 

You still have plenty of time to get to a wifi zone and load 'em up in time for some heavy rotation before the show.
