Best Rap/Sung Collaboration
This category remains the same from previous years and honors a newly recorded performance by artists (singing vocalists and rapping artists who do not normally perform together. Both artists must be credited as featured artists, and there must be "significant performance by the collaborative artist(s) beyond what might be considered merely accompaniment." The award is given to and based on the performances of the artists, not on songwriting, production or mixing. (Info)
Beyonce & Andre 3000 - "Party" (from 4)
Beyonce's latest album was an uneven mishmash of styles and songs performed really well, but then so were all of her previous albums, and 4 is by far the most intelligent of the bunch. As was the case with much of the material, "Party" got a mixed reception from critics and fans, but you might find reactions to be revealing: those looking for a hot dance floor jam generally found it "disappointing," while erudite critics commended the 80s synth production (by Kanye West, as it happens) and girl group harmonies, and hip-hop fans invariably praised Outkast rapper Andre 3000's effortless verse, which includes an extended (and deceptively filthy) dairy metaphor. This isn't the version you might have heard on urban radio; that remix features a shorter verse by Best New Artist nominee J. Cole, who originally recorded verses for the album track.

I may have trouble filling up enough space with this one, but one can try. This is a chilly piece, mostly run by Drake, who sings and raps about celebrity and fame and being young and so forth. Rick Ross and Lil Wayne throw in a couple comments between meals, as they do, and if you don't feel like jumping off a bridge or at least having a stiff one afterward then your resistance to melancholia is stronger than mine.
Dr. Dre, Eminem & Skylar Grey - "I Need A Doctor"

Rihanna & Drake - "What's My Name" (from Loud)

Kelly Rowland & Lil Wayne - "Motivation" (from Here I Am)

Kanye West, Rihanna, Kid Cudi, & Fergie - "All Of The Lights" (from My Beautiful Dark Twisted Fantasy)
Only four artists won the nomination for this sprawling track from West's snubbed album, but don't be fooled: there are no fewer than fourteen guest vocalists smashed into this single, some you can pick out and others not so much. There's Alicia Keys (you can pick her out), there's John Legend (ditto), there's...Elton John? La Roux's Elly Jackson? It's all in the mix, which is kind of like cooking with expensive wine, but what else can one expect from Kanye West? Fergie comes on and raps, and Rihanna provides the sung hook - why not? I'd call the whole thing a bit over-inflated, but few seem to agree with me. The song is also up for Song of the Year and Best Rap Song, both songwriting awards.
Snubs
This category missed a number of particularly deserving collaborations, some of them more so than any of the six that made the cut. A few I would have liked to see here include Ke$ha & Andre 3000 for "The Sleazy Remix," Nicki Minaj & Ester Dean for "Super Bass," and Jennifer Lopez & Lil Wayne for "I'm Into You."
Prediction - I wouldn't feel terrible putting money on Rihanna and Drake and "What's My Name?", but not a lot of money.
Vertigo Shtick's Pick - Look, Beyonce is great, and I'm not blind to the merits of Kanye's big Robert Altman number. but Kelly Rowland and Lil Wayne deserve this award for "Motivation."
