2015 is going to end with a playlist with some of the year's biggest hits. In addition to Carrie Underwood and One Direction bringing in 2016 on Dick Clark's New Year's Rockin' Eve, Luke Bryan, Demi Lovato, and Wiz Khalifa have all been added to the NBC lineup.

The annual Time Square ball drop and concert will be headlined by Underwood, but according to Billboard, she won't be at it alone. She will be joined by her fellow country star Luke Bryan. Demi Lovato will represent pop while Wiz Khalifa will be bringing along some hip-hop flavor with Charlie Puth.

Though the songs that Bryan, Lovato, Underwood and One Direction will be performing have yet to be announced, it's safe to assume that Khalifa and Puth will be doing a rendition of their Furious 7 hit "See You Again." The song, which is a tribute to deceased Fast and Furious star Paul Walker, was one of the biggest hits of the year. The song was No. 1 on the Billboard Hot 100 for 12 non-consecutive weeks from April to July, thanks to its heartfelt lyrics and crossover appeal.

2015 was a big year for Lovato and Bryan, too. Lovato released her new album Confident in October. Led by singles "Cool for the Summer" and "Confident." Along with a sexy makeover, the follow-up to 2013's DEMI showcased that Lovato is no longer that sappy Disney star. As for Bryan, he has a multi-week No. 1 album with Kill the Lights.

Dick Clark's New Year's Rockin' Eve will be hosted by Ryan Seacrest in New York City along with Underwood. Fergie will lead a party in Los Angeles with One Direction. The show is set to air, obviously, on Dec. 31.
