Last time around, Adele was Queen of the Grammys. But which artists' names will be called tonight, when the nominations for the 55th annual Grammy Awards are announced?

The nominees in the top categories will be revealed on the CBS prime-time special "The Grammy Nominations Concert Live!!": co-hosted by Grammy winners Taylor Swift and LL Cool J, and airing live from Nashville, Tenn., at 10 p.m.

In addition to the revelation of the nominees for the music industry's highest honor, the special will also feature musical performances by Maroon 5, fun., Ne-Yo, The Band Perry, rock legends The Who and country stars Hunter Hayes, Luke Bryan and Dierks Bentley.

So, who'll be racking up the nods tonight? Carly Rae Jepsen is one artist whose chart domination this year can't be ignored, but she may not figure in some of the top categories.

"I think that she is going to certainly get a Best New Artist nomination but the popular songs, the ones that you can never get away from on radio, aren't necessarily the ones that the Grammy voting committee gives nominations to," editor Tye Comer said.

As a result, he says, a Record of the Year nod might not be a lock, but, he added, "I definitely think that Jepsen can expect to have a few nominations under her belt."

But what would Jepsen's reaction be to hearing her name called tonight?

"I think I would just sit down into a little ball and cry," Jepsen said. "I think that's what I would do. And then scream a little bit after that. I think that would be too much. That would be the cherry on top of a really great year."

Comer also told ABC News that unlike last year, when it was wall-to-wall Adele, Grammy is likely to spread the love among a handful of nominees in the top categories of Record of the Year, Song of the Year, Album of the Year and Best New Artist. The one name he's convinced will figure in all four categories: acclaimed R&B artist Frank Ocean.

"I do think that he created one of the best albums of 2012," Comer says of Ocean's "Channel Orange" album, which even Adele raved about via Twitter. "I think that not only is he a shoo-in for the Best New Artist nomination, I think that he could surprise people with a Best Song and Best Record nomination for 'Thinkin' 'Bout You,' and possibly even a Best Album nomination."

Comer said British folkies Mumford & Sons are also shoo-ins for many nominations, including Record of the Year for "I Will Wait." Also on the list: fun., and their hit "We Are Young." Comer says the group will get a nod for Best New Artist, even though their latest album isn't their first release.

"The way the Grammy voting works, if you have not been nominated … before, then you can be up for the Best New Artist category," Comer explained. "So, I think that not only will fun. find themselves certainly in the running for Best New Artist but I think that 'We Are Young' is also going to find itself as a strong contender for Record of the Year."

Also a contender for Record of the Year, Comer says, is Gotye's "Somebody That I Used to Know." And what about perennial Grammy favorite Taylor Swift? Comer says her name will be in the mix, but not a lot.

"Unfortunately, the album that she put out, "Red," isn't going to be eligible for the nominations this year," Comer said, noting that it was released after the Grammy cutoff date. "But 'Never Ever Getting Back Together' is certainly a song that was on everyone's radar. I don't think the Grammy committee will overlook it and it is quite possible that it could get a Record or Song nomination this year."

In addition, Comer said, veteran rockers like Bruce Springsteen, Paul McCartney, Lionel Richie, Bonnie Raitt and Bob Dylan mighty also see their latest albums recognized.

Here are a few more artists, albums and songs that might be in the mix tonight: Maroon 5 for "Overexposed" and its two big hits "Payphone" and "One More Night," Phillip Phillips, for "Home," One Direction for Best New Artist, John Mayer for his album "Born & Raised," Katy Perry for "Wide Awake," Florence + the Machine for "Ceremonials," Rihanna for "Talk that Talk," Alicia Keys for "Girl on Fire" and Pink for "The Truth About Love."
