Fast Life Yungstaz are experiencing the “Taylor Swift effect.”

In a fan-posted clip of an interview with Ryan Cameron on Wednesday, the hip-hop group — Myko McFly, Vee and Mook — opened up about the success they’ve been experiencing surrounding their 2009 classic “Swag Surfin’” thanks to the “I Can See You” musician, 34, who was spotted dancing to the song while supporting her boyfriend Travis Kelce at a Kansas City Chiefs game on Jan. 13.

“She’s a big help. I’ll say that much,” the band said. “She got our streams up like 700% right now on Spotify, Apple Music.”

F.L.Y. then revealed that they’ve gained more than 20,000 new followers on YouTube.

“Shout out to Tay-Tay,” the “Mr. Lenox” group said. The Taylor Swift Effect is real.

When fans hear “Swag Surfin’” on the Chiefs’ home turf at Arrowhead Stadium, an official dance break commences. They sway from side to side as the hip-hop track plays, and Swift joined in on the excitement with the other attendees. Joining her in the fun was Brittany Mahomes and Travis’ mom, Donna Kelce as they watched the Chiefs beat the Miami Dolphins  26-7.

Fans Swift’s spirit during the song and the official Sunday Night Football account shared a clip of her dancing alongside Donna, 71, and Brittany, 28, as fans in front of their suite watched and recorded the moment. The NFL shared a clip of their moves, too.

In a January episode of Travis’ podcast with his brother, New Heights with Jason and Travis Kelce, the NFL star called the song “a classic” for the team and revealed that it has been a staple to hype up his team since he joined in 2013.

When Jason Kelce asked about the meaning of the track, the tight end, 34, said it’s “a huge fourth quarter, big time moment,” and often soundtracks an important defensive drive. “They play a highlight video that has ‘Swag Surfin’ on it as the song and it gets everybody hype.”

The brothers also brought up a video from the Chiefs New Year’s Eve game where linebacker Willie Gay Jr. suggested the song play to get attendees excited, and once it started, he and his teammates began dancing on the sidelines with the crowd, and the mood immediately shifted.
