Album of the Year
The Hot 100 Hitmaker: Taylor Swift, Red (shown)
''It's spawned so many great hits and it's just really solid songwriting front to back, as usual. And she's also Taylor Swift, so she always wins something.''
The Crossover Pop Star: Sara Bareilles, The Blessed Unrest
''She's who I'm voting for, but Taylor Swift has the best chance of winning — and totally deserves it. Those are two monumentally good albums for completely different reasons.''
The A-List Producer: Kendrick Lamar, Good Kid, M.A.A.D City
''I don't know why Yeezus is not in this category. I have to say, who's going to win is Taylor. There's a huge voter bloc out there for her.''

Record of the Year
The Hot 100 Hitmaker: Robin Thicke, ''Blurred Lines''
''That was a cultural moment, for sure. It's one of a couple of anti-hits this year where it doesn't sound right off the bat, but [then] it just sucked everybody in.''
The Crossover Pop Star: Lorde, ''Royals'' (shown)
''It's an amazing song — the production, her performance. It's like, you look at the nominees and it's a real interesting year, but that's the one that's totally up there on Mars.''
The A-List Producer: Bruno Mars, ''Locked Out of Heaven''
''The song, the vocals, the hook, everything is amazing. 'Blurred Lines' is great, but too big, too poppy. 'Get Lucky' — great record, a little too fluffy. 'Royals' is tough [competition], but it kind of sounds like a demo.''

Song of the Year
The Hot 100 Hitmaker: Katy Perry, ''Roar''
''Look, I think 'Same Love' will win because it's a more important song historically. However, I feel like 'Roar' and 'Locked Out of Heaven' and even 'Just Give Me a Reason' are just traditionally more classic songs.''
The Crossover Pop Star: Pink feat. Nate Ruess, ''Just Give Me a Reason'' (shown)
''Just because of strictly what I believe songwriting is: melodies, verses, chords, lyrics, bridge, all these parts coming together to create something bigger.''
The A-List Producer: Pink feat. Nate Ruess, ''Just Give Me a Reason''
''It really touches a nerve with everyone. It deals with love in such a unique way.''

Best New Artist
The Hot 100 Hitmaker: Macklemore & Ryan Lewis (shown)
''I'm going to say either Macklemore, who I love and think is super-talented and a real breakout, or Kacey Musgraves, who is such an incredible songwriter.''
The Crossover Pop Star: Kendrick Lamar
''I think he's the most exciting, when you think about someone who did not exist to the mainstream public a year ago.''
The A-List Producer: James Blake
''They're all really great and deserving. I'm going to say just as a sleeper, Bon Iver-style, who's the least publicly visible, new-artist-y pick? James Blake is the most fresh.''

Best Pop Vocal Album
The Hot 100 Hitmaker: Lana Del Rey, Paradise
''Can I just say that I think [Justin Timberlake's] The 20/20 Experience is the most indulgent, regurgitated piece of crap? I'm so mad because I'm such a big JT fan, and it all sounds like Justified rejects. But Lana, she's incredible. I think she has a really unique voice and a beautiful aesthetic.''
The Crossover Pop Star: Bruno Mars, Unorthodox Jukebox (shown)
''Gotta go with Bruno Mars. As a vocalist, he gets it done.''
The A-List Producer: Bruno Mars, Unorthodox Jukebox
''Robin's got something special. Justin's obviously got something special.... [But] he's lost a little something over the years vocally. Bruno just has an urgency in his voice. And when you write your own stuff, it gives you an edge on how the vocals are going to come across.''

Best Pop Duo/Group Performance
The Hot 100 Hitmaker: Robin Thicke, ''Blurred Lines'' (shown)
''I would give this one to Robin Thicke, because of what it did, because of how crazy it was. Like, it's gotta win something — if they don't win something, it'll be a crime.''
The Crossover Pop Star: Pink feat. Nate Ruess, ''Just Give Me a Reason''
''This has a classic '80s beautiful pop duet [sound]. It's possible 'Blurred Lines' could get it, but what's playing at someone's party isn't necessarily what people are going to vote for at the Grammys.''
7 of 13
Best Rock Album
The Hot 100 Hitmaker: Queens of the Stone Age, ...Like Clockwork (shown)
''I mean, it's a legendary group of dudes together. Although I think Black Sabbath will win.''
The Crossover Pop Star: Queens of the Stone Age, ...Like Clockwork
''They made a really amazing rock album, in terms of what I think rock music actually is.''
The A-List Producer: David Bowie, The Next Day
''Because he made an amazing album, and because of the legend factor. As a work, as a total album, I think it has to be this.''
8 of 13
Best Alternative Music Album
The Hot 100 Hitmaker: Nine Inch Nails, Hesitation Marks
''I'm a big fan. I always [loved] Trent Reznor, so I'm hoping to see him on stage.''
The Crossover Pop Star: Vampire Weekend, Modern Vampires of the City (shown)
''No doubt. It just is the best alternative album of the year.''
The A-List Producer: Tame Impala, Lonerism
''I'm just one hair away from saying Vampire Weekend. But Tame Impala are a little more exciting. They have a really fresh sound. It's like an exotic bird — it stands out.''
9 of 13
Best Rap Album
The Hot 100 Hitmaker: Kendrick Lamar, Good Kid, M.A.A.D City
''It was the most innovative and refreshing of the bunch. Jay Z's great, but it's just more Jay Z to me. Like, 'Eh, I've heard it.'''
The Crossover Pop Star: Kanye West, Yeezus (shown)
''As for Macklemore & Ryan Lewis, I think the Grammys don't get hung up on buzz as much as people think they do.''
The A-List Producer: Kanye West, Yeezus
''That's the easiest one. It's a work of art, something that changes music and changes culture.''
10 of 13
Best Rap Song
The Hot 100 Hitmaker: Drake, ''Started From the Bottom'' (shown)
''[Jay Z and Justin Timberlake's] 'Holy Grail,' the beat is amazing but it doesn't make you feel anything emotionally. Drake, there's a theme, there's a story, I know what you're talking about.''
The Crossover Pop Star: A$AP Rocky, ''F**kin' Problems''
''He will and should win. It kills everything else in the category.''
11 of 13
Best Country Album
The Hot 100 Hitmaker: Kacey Musgraves, Same Trailer Different Park
''I absolutely adore this album. I mean, of course Taylor Swift is there too, but I don't think it's fair. She's singing about hipsters and breakdowns, and it's not country!''
The Crossover Pop Star: Taylor Swift, Red
''I think it's the album of the year, but I also think as far as this category goes, she's done a good job at sowing her country roots into a different sound. She managed to keep it in her genre while also testing the boundaries.''
The A-List Producer: Blake Shelton, Based on a True Story (shown)
''Blake is kind of the patriarch of country music.''

Best Country Song
The Hot 100 Hitmaker: Miranda Lambert, ''Mama's Broken Heart''
''This one tugs at the heartstrings a little bit, and it just speaks to me more than the other ones.''
The Crossover Pop Star: Kacey Musgraves, ''Merry Go 'Round'' (shown)
''She's a really exciting artist and deserves to take something home, and that's the place where she really can.''
13 of 13
Best Dance Album
The Hot 100 Hitmaker: Daft Punk, Random Access Memories (shown)
''People love Daft Punk. They took a chance [doing] a concept album, and I think that's really cool. They're like the grandfathers of techno music. Well actually, Kraftwerk is the grandfather of techno music, but Daft Punk is like the uncle.''
The A-List Producer: Daft Punk, Random Access Memories
''It's a seminal album, even if they didn't quite nail it. It was a bit more of a documentary than a dance/electronica album.''
