The Grammys are music's biggest night, both literally and figuratively.
The ceremony, which takes place in LA on Sunday night, runs for a staggering eight hours, attracting the biggest stars in pop, rock, country and hip-hop.
Organisers will hand out 94 awards, recognising everything from best pop album to best choral performance.
Beyoncé and Taylor Swift have both confirmed their attendance, as they square off in the album of the year category for the first time since 2010 (Swift won on that occasion, fact fans).
There'll also be performances from Charli XCX, Sabrina Carpenter, Benson Boone, Shakira, Stevie Wonder, Teddy Swims and Raye - and an in memoriam tribute to Thriller producer Quincy Jones.
Here's everything you need to know about the ceremony.
1) Who's going to win album of the year?
The big question of the night is whether Beyoncé will finally win album of the year, after four previous losses in the category?
During last year's ceremony, her husband Jay-Z addressed the oversight, telling the audience: "I don't want to embarrass this young lady, but she has more Grammys than everyone and never won album of the year. So even by your own metrics, that doesn't work."
Beyoncé's latest record, Cowboy Carter, is a wildly ambitious attempt to contextualise and commemorate the black roots of country music. It's the sort of thing that delights Grammy voters, who traditionally prefer albums that elevate America's musical history over contemporary, cutting-edge productions.
But the album's excessive length - including a few weaker tracks in its latter half - could count against it.
Billie Eilish is currently the bookmakers' favourite with her third album Hit Me Hard and Soft. Mixing passionate power ballads with violent electronic shifts and hip-hop swagger, it marks a new evolution in the star's songwriting partnership with her brother, Finneas.
Charli XCX's Brat is a career-defining pop record that became a cultural phenomenon. The best-reviewed album of 2024, it's probably too abrasive for the Grammys' more conservative voters, but that's their loss.
And you'd have to be crazy to ignore Taylor Swift. Her 11th album, The Tortured Poets Department, was the biggest-seller of last year; a fact that will undoubtedly be taken into account, even if the record is one of her weaker efforts.
If she wins, Swift will collect her fifth album of the year trophy - more than any other artist in Grammy history.
