“Let ’Em In,” the title of a Wings hit from 1976, also seemed to be the Grammy Screening Committee’s guiding principle in deciding who to allow to compete for best new artist this year. Sabrina Carpenter, who is on her sixth album, was ruled eligible, as was Megan Moroney, who had a No. 30 hit on the Hot 100 in May 2023 with “Tennessee Orange.”

Moroney is nominated for new artist of the year the CMA Awards for the second year in a row. HARDY, who was nominated in that category at the CMAs in both 2021 and 2022, is also eligible this year. So is Cody Johnson, who was nominated in that category at the CMAs in both 2019 and 2022.

How can an artist who has released six albums be eligible for best new artist? Because, while the Grammys set a minimum number of releases an artist must have to qualify in this category (five singles/tracks or one album), there is no maximum. Instead, the Grammys’ rules and guidelines booklet says nominations for the honor hinge on when “the artist had attained a breakthrough or prominence” — and it delegates that determination to a screening committee.

So Carpenter’s eligibility came down to whether the screening committee thought she had achieved prominence as of Sept. 15, 2023, the last day of the previous eligibility year. At that point, the highest she had ever climbed on the Billboard Hot 100 was a decidedly decaf No. 48, for “Skin” in February 2021. The committee decided that so-so showing did not constitute prominence, and that she made her big breakthrough in this eligibility year.

As for the other artists mentioned, the committee likewise decided that this was the year they achieved a breakthrough or prominence. The committee’s oft-stated aim is to be inclusive rather than exclusive, and they demonstrated that this year.

Many of the eligible artists have been nominated for new artist awards at other awards shows in the past year. Chappell Roan, who many see as this year’s Grammy front-runner in this category, won best new artist at the VMAs in September. Benson Boone, Shaboozey and Teddy Swims were on the initial list of nominees at the VMAs but they didn’t make the final three. They’re all eligible here.

Moroney, Shaboozey and Nate Smith are all nominees for new artist of the year at the CMAs on Nov. 20. They are eligible here.

4Batz, Bossman Dlow, October London and Sexxy Red were nominated for best new artist at the BET Awards and are eligible here. Bossman Dlow, Sexyy Red and Tommy Richman are nominated for best new artist at the upcoming BET Hip Hop Awards and are eligible here.

The Red Clay Strays won emerging act of the year at the Americana Music Honors and Awards in September. They’re also eligible here and will likely do well with Grammy voters.

RAYE, who won best new artist and swept many other awards at the Brit Awards in March, is likewise eligible here.

Other buzzy artists on the eligibility list, not already mentioned, include Artemas, Ateez, Barry Can’t Swim, beabadoobee, Central Cee, Ivan Cornejo, Dasha, Djo, Doechii, Sophie Ellis-Bextor, Feid, Fireboy DML, Fletcher, Flo Milli, 42 Dugg, Grupo Frontera, Kate Hudson, Knox, David Kushner, The Last Dinner Party, Le Sserafim, Carin Leon, LISA, Mannequin Pussy, Lizzy McAlpine, Michael Marcagi, Reneé Rapp, Rema, Maggie Rose, Royel Otis, Jojo Siwa, Myles Smith, Brittney Spencer, Tigirlily Gold, Myke Towers, Waxahatchee, Koe Wetzel, Remi Wolf and Young Miko.

Artists are allowed to appear on the entry list for best new artist three times, after which they are ruled ineligible for future consideration. That rule came into play this year with Tate McRae, who had been entered three previous times and thus could not compete again.

As it turns out, almost every artist who pundits thought might be eligible made the list. Two who did not are GloRilla and Anne Wilson, both of whom had previous Grammy nominations. That almost always results in disqualification.

The rules in this category have changed over the years as the Recording Academy has struggled to strike just the right balance: not too strict, not too lenient. In the past, the academy has sometimes disqualified artists for reasons that may now seem petty; take Whitney Houston, who had recorded a couple of duets prior to releasing her debut album and was therefore deemed ineligible, or singer-songwriter Richard Marx, who had contributed a song to a soundtrack. Other times, the academy has leaned too far in the other direction. Robert Goulet won in 1963, two years after he became a star in the Broadway musical Camelot. When Alessia Cara claimed the prize in 2018, it was nearly two years after her ballad “Here” hit the top five on the Hot 100.

Three past winners for best new artist — Crosby, Stills & Nash (who won in 1970), Jody Watley (1988) and Lauryn Hill (1999) — wouldn’t be eligible under today’s rules. David Crosby, Stephen Stills and Graham Nash were all already known for their work in previous groups, as were Watley (in Shalamar) and Hill (Fugees).

A total 323 artists are eligible for best new artist this year, down from 405 last year. This year’s tally is the lowest in this category in five years.

By allowing Carpenter to compete for best new artist this year, the Recording Academy has made the race more competitive and unpredictable. What might have been a shoo-in for Chappell Roan will now be a more spirited contest. Place your bets.
