Interesting, random trivia about the top honor in pop music.

• Taylor Swift’s “Shake It Off” is nominated for Record of the Year and Song of the Year. When the video for “Shake It Off” was being filmed earlier this year, the song had not been released and yet. It was kept so secret that outside of the soundstage, hard rock music was blasted to prevent anyone unauthorized from hearing it prematurely.

• The powerful choir on Sam Smith’s ROTY and SOTY nominee “Stay With Me” consists of 20 male voices. A choir? Nope. It’s all Smith himself, thanks to digital layering and other studio magic.

• Beyoncé released her self-titled album, Beyoncé, exclusively to iTunes late last year. It earned a nomination for Album of the Year, the first time a digital-only album has earned that honor.

• Beyoncé’s six nominations bring her lifetime total to 53. She’s now the most nominated female artist in Grammy history, and she’s only 33.

• If Iggy Azalea wins Best New Artist, she’ll be the second female rapper to win, and only the second Australian to win it. (The other rapper was Lauryn Hill in 1999. The other Australian was Men at Work in 1983.)

• If HAIM wins Best New Artist, it will be the first time a band comprised of sisters takes the award. The only other sister act ever nominated? Wilson Phillips in 1991, who lost to Mariah Carey.

• Meghan Trainor’s first single “All About The Bass,” a ‘60s throwback about positive body image, was a surprise #1 hit earlier this year, and it surprised music industry pundits when it earned nominations for ROTY and SOTY. Trainor was a songwriter before turning to performing (she wrote songs for Rascall Flatts and other bands). She only sang the song after Beyoncé turned it down.
