The trophies won't be handed out until Feb. 13, but that doesn't mean you can't weigh in on your favorite of the five nominated choices.
Arcade Fire's The Suburbs
The album by the Canadian indie rockers was released in August and was described by frontman Win Butler as "a mix of the Depeche Mode and Neil Young." It drew two other nods this year: Best Alternative Music Album and Best Rock Performance By A Duo Or Group With Vocals.
Eminem called upon fellow superstars Pink and Rihanna to back him up on this one, which shot straight to the top of the charts when it was released in June. Critics generally liked it, with Entertainment Weekly seeing "flashes of new maturity" in the work. It's up for multiple awards, including Best Rap Album.
Lady Antebellum's Need You Now
The group's sophomore effort debuted at No. 1 on the Billboard 200 chart and spawned the catchy hit – about an ill-advised late-night phone call made out of loneliness – of the same name.
Lady Gaga's The Fame Monster
The album, technically an EP, counts Beyoncé as one of its guests and deals with the darker side of fame. The Fame Monster spawned mega-singles including "Bad Romance" and "Alejandro."
Katy Perry's Teenage Dream
Russell Brand's wife is responsible for one of the songs of 2010, "California Gurls," the lead single from this disc. Teenage Dream went straight to No. 1 when it was released in August, and is also nominated for Best Pop Vocal Album.
