Primary Wave’s annual pre-Grammy party went down Saturday night at the Waldorf Astoria Beverly Hills, and this year, for the first time, it celebrated Billboard No. 1s.

So it makes sense that a crowd of hitmakers was in the building to celebrate Grammy Weekend, including Jon Bon Jovi, who had just been honored the night prior as MusiCares Person of the Year and is the voice of four Billboard Hot 100 No. 1 hits with his namesake band. Melissa Etheridge was also there, alongside wife Linda Wallem, and she’s a Billboard chart-topper too, including the Adult Contemporary No. 1 smash “I’m the Only One.”

Then there was Bell Biv DeVoe — the trio of Ricky Bell, Michael Bivens and Ronnie DeVoe — who scored three No. 1s on Billboard‘s Hot R&B/Hip-Hop Songs chart in their early ’90s heyday. They were the perfect people for Billboard‘s Rania Aniftos to ask “what is the key to making a hit song?” on the red carpet Saturday night.

“Be yourself, have fun, make sure you’re enjoying it,” Bell offered. “Make sure it’s what you would really listen to when you go to the clubs or jump in your car. Just keep it true in that aspect.”

Bivens chimed in next: “I would say get a hot beat. Don’t nothing happen without the beat. Then go straight to the chorus and get something that they want to remember. And then just tell a story that you think connects to men and women.”

Finally, DeVoe said, “It’s about that moment in time too, like being real as far as what you’re feeling in your life at that time. The biggest albums were about a moment in time in any given artist’s career. Whether it’s Prince, Purple Rain or Mary J. Blige, What’s the 411? There’s so many classics based on people’s pain and their victory at any time. A song should speak to that.”

CeeLo was in charge of the night’s music, spinning everything from Usher’s “Yeah!” and Too $hort’s “Blow the Whistle” to his own “F**k You! (Forget You),” a No. 1 hit on Billboard‘s Pop Airplay chart in 2011.

Also at the Waldorf Astoria for the party: Lauren Spencer-Smith, Fifth Harmony alumni Ally Brooke & Dinah Jane, Grandmaster Flash, Gavin Rossdale, “Lovin On Me” co-writer & co-producer Sean Momberger, Johnny Gill, Bonnie McKee, Israeli & Palestinian boy band as1one, Eric Benét, charlieonafriday, Pat Houston, Donna Houston, Damien “DDOT” Washington, Domani Harris, Armani White, James Charles, Crystal Kung Minkoff
