Sunday's Grammy Awards will provide an impressive slate of performers that spans every genre. (Even a classical artist will make an appearance.) Whether we're in store for anything as wild as last year's LL Cool J-fronted Adam Yauch tribute or as rousing as Justin Timberlake and Jay Z's collaboration is yet to be seen, but you can start placing your bets for this year's watercooler moment based on the roster below.
BILLIE JOE ARMSTRONG AND MIRANDA LAMBERT
The first in a handful of unlikely combinations finds the Green Day frontman and the beloved country singer teaming up for a tribute to the late Phil Everly. Green Day's "¡Cuatro!" has a nod for Best Music Film, while Lambert's "Mama's Broken Heart" could score Best Country Solo Performance or Best Country Song.
SARA BAREILLES AND CAROLE KING
Bareilles received a surprise nod for Album of the Year ("The Blessed Unrest") and cracked Best Pop Solo Performance ("Brave"). King is the 2014 MusiCares Person of the Year, and she's already been saluted once this weekend with an all-star tribute concert.
BEYONCE AND JAY Z
"Beyonce" wasn't released within the eligibility period, but Jay Z has nine nods: Best Pop Duo/Group Performance ("Suit & Tie," with Justin Timberlake), Best Rap Performance ("Tom Ford"), Best Rap/Sung Collaboration ("Part II" with Beyonce, and "Holy Grail" with Justin Timberlake), Best Rap Song ("Holy Grail"), Best Rap Album ("Magna Carta...Holy Grail"), Best Music Video ("Picasso Baby: A Performance Art Film" and "Suit & Tie") and Best Recording Package ("Magna Carta...Holy Grail").
GARY CLARK JR.
Clark is up for Best Rock Song ("Ain't Messin' Around") and Best Traditional R&B Performance ("Please Come Home").
DAFT PUNK, NILE RODGERS, PHARRELL WILLIAMS AND STEVIE WONDER
Daft Punk, Williams and Rodgers scored two nods together for "Get Lucky" -- Record of the Year and Best Pop Duo/Group Performance. Daft Punk's "Random Access Memories" is up for Album of the Year, Best Dance/Electronica Album and Best Engineered Album (Non-Classical). Williams has an additional nod for Producer of the Year (Non-Classical), and he can count the two shoutouts "Blurred Lines" received as well. Wonder is nominated for Best R&B Song as a featured artist on PJ Morton's "Only One."
Hayes, 22, received his fourth Grammy nomination this year, for Best Country Solo Performance ("I Want Crazy").
The Memphis-based Three 6 Mafia rapper released his third solo album, "Stay Trippy," in August. He is not a nominee.
KENDRICK LAMAR AND IMAGINE DRAGONS
Lamar is one of the awards show most feted artists. He's up for Album of the Year and Best Rap Album ("Good Kid, M.A.A.D City"), Best New Artist, Best R&B Performance ("How Many Drinks?" with Miguel), Best Rap Performance ("Swimming Pools (Drank)"), Best Rap/Sung Collaboration ("Now or Never" featuring Mary J. Blige) and Best Rap Song ("F--kin' Problems" with ASAP Rocky, Drake and 2 Chainz). In an unlikely move, Imagine Dragons will join the celebrated rapper onstage. They'll collaborate on the alternative band's hit "Radioactive" and Lamar's "m.A.A.d city." "Radioactive" is up for Record of the Year and Best Rock Performance.
Legend could take home Best R&B Album for "Love in the Future."
Lorde was snubbed for Best New Artist, but "Royals" made away with slots in Record of the Year, Song of the Year and Best Pop Solo Performance. Her debut album, "Pure Heroine," is up for Best Pop Vocal Album.
MACKLEMORE AND RYAN LEWIS WITH MADONNA
"The Heist" is up for Album of the Year and Best Rap Album, "Can't Hold Us" has a Best Music Video nod, "Same Love" landed in Song of the Year, and "Thrift Shop" could take home Best Rap Song and Best Rap Performance. Madonna, who is not a nominee this year, will join the rapper-producer duo for "Same Love."
METALLICA AND LANG LANG
"Metallica Through The Never" has a nod for Best Recording Package. Celebrated concert pianist Lang Lang is the Grammys' cultural ambassador to China. What's in store for these unlikely bedfellows is anyone's guess.
Both McCartney and fellow Beatles bandmate Ringo Starr are scheduled to perform at the awards, where they'll receive a Lifetime Achievement Award on behalf of The Beatles. It's not confirmed that the two will appear together, though, so for now we're forced to assume they're doing the solo thing during their performances. "Cut Me Some Slack," McCartney's collaboration with the surviving members of Nirvana, is up for Best Rock Song, and "Little Kisses" is up for Best Music Film.
Starr will receive a Lifetime Achievement Award as well and, if our hopes hold steady, take the stage alongside McCartney for a reunion.
Musgraves emerged as a surprise favorite among Grammy voters, landing spots in Best New Artist and Best Country Album ("Same Trailer, Different Park"). She also has two opportunities to win Best Country Song, one for her hit "Merry Go 'Round" and another for co-writing Miranda Lambert's "Mama's Broken Heart."
Perry's "Prism" narrowly missed the cutoff for the album categories, so the singer will have to settle for nominations for Song of the Year and Best Pop Solo Performance ("Roar").
PINK AND NATE RUESS
The duo's "Just Give Me a Reason" is up for Song of the Year and Best Pop Duo/Group Performance.
ROBIN THICKE AND CHICAGO
1970s rock band Chicago will join Robin Thicke, who's in contention for three awards. "Blurred Lines" could nab Record of the Year or Best Pop Duo/Group Performance, and the album of the same name is up for Best Pop Vocal Album.
To no one's surprise, Swift is one of the night's most-nominated artists. "Red" could win Album of the Year or Best Country Album, while "Begin Again" is a contender for Best Country Song and "Highway Don't Care," her collaboration with Tim McGraw and Keith Urban, is among the Best Country Duo/Group Performance finalists.
The popular New Orleans trumpet and trombone player will bring his funky jazz to the Grammy stage, even though he isn't nominated.
Urban is up for just one award: Best Country Duo/Group Performance, for "Highway Don't Care."
MERLE HAGGARD, KRIS KRISTOFFERSON, WILLIE NELSON AND BLAKE SHELTON
Country fans will lap up this all-star performance that finds the quartet reportedly performing "The Highwayman," "Mammas, Don't Let Your Babies Grow Up To Be Cowboys" and "Okie From Muskogee." Kristofferson is the recipient of the 2014 Recording Academy Lifetime Achievement Award, and Shelton is up for Best Country Album ("Based on a True Story...") and Best Country Solo Performance ("Mine Would Be You").
NINE INCH NAILS, QUEENS OF THE STONE AGE, DAVE GROHL AND LINDSEY BUCKINGHAM
This impressive rock ensemble, who've all collaborated on one another's projects over the years, will close out the show. Queens of the Stone Age's "My God Is the Sun" is up for Best Rock Performance, and "...Like Clockwork" is one of the Best Rock Album contenders. Nine Inch Nails' "Hesitation Marks" could win Best Alternative Music Album, and "Cut Me Some Slack" could net Grohl (along with McCartney and the other surviving members of Nirvana) the trophy for Best Rock Song. The album for Grohl's "Sound City," a 2013 documentary that features all of the aforementioned performers, is nominated for Best Compilation Soundtrack for Visual Media.
