There’s one big difference between Sunday night’s Billboard Music Awards and every other music award show on television: the winners are a true reflection of not just what fans like, but what they actually consume and spend money on.

“Those charts are what make our award show,” Billboard’s co-director of charts, Keith Caulfield, told me this week. “That’s the beauty of it. This award show is truly based on your performance on the Billboard charts throughout the year.”

The BBMAs serve as an annual scoreboard of sorts for the music industry’s biggest names. We’ll find out where the stars rank Sunday night at 8 p.m. on ABC.

“Billboard gets to honor the most popular artists, albums and songs of the past year on a great TV show, and we get to have amazing performances and it’s a star-studded event,” Caulfield said. “I’m really looking forward to the show.”

The list of performers alone could make this year’s program one of the more memorable in recent memory. Britney Spears, receiving the Millennium Award, will perform a medley of her hits. Justin Bieber will do the same. Rihanna is slated to sing on the show, almost exactly 10 years to the date she scored her first Billboard Hot 100 chart-topper. And Madonna will perform a tribute to the late Prince.

That doesn’t even scratch the surface: Celine Dion, Gwen Stefani and Blake Shelton, Nick Jonas and Tove Lo, Demi Lovato, Meghan Trainor, Fifth Harmony, Pink and Ariana Grande are also set to take the stage inside the brand new T-Mobile Arena in Las Vegas.

As for the awards, The Weeknd is a finalist in 16 categories, leading all artists. Bieber follows him with nods in 11 categories. Taylor Swift and Adele are each a finalist in eight categories. Perhaps taking a cue from Swift’s “Bad Blood” music video premiere at last year’s BBMAs, Adele will unveil her video for the single, “Send My Love (To Your New Lover)” during the broadcast Sunday.

Appropriately, Swift holds the all-time high mark for wins at the show with 20. Adele has the record for most wins in one night with 12, which she scored back in 2012 off the success of “21.”

The Billboard Music Awards are produced by dick clark productions. Westwood One, the radio network owned by Cumulus Media, is once again an official partner of this year’s show. For the fourth consecutive year, I will broadcast from Las Vegas for the BBMAs. In addition to interviewing stars backstage Saturday and on the red carpet Sunday, we’ll have a full recap from Vegas on Monday evening.
