iHeartMedia's KOST 103.5 in Los Angeles has once again ushered in the holiday season, officially flipping to nonstop festive music this morning for the 25th consecutive year. The annual tradition was celebrated live on the Ellen K Morning Show, where Gwen Stefani, Pentatonix and LeAnn Rimes joined host Ellen K to "flip the switch" to holiday programming at 8am.
Listeners can now enjoy a mix of timeless classics from artists such as Burl Ives and Brenda Lee, alongside modern favorites from Mariah Carey, Michael Buble and Kelly Clarkson. The all-holiday lineup will continue through the end of the season.
"KOST has been Southern California's holiday music destination for 25 years, and we're thrilled to continue spreading joy and festive cheer this season," said John Peake, Executive Vice President of Programming for iHeartMedia Los Angeles and Program Director of KOST 103.5. "Our listeners make this celebration special, and we're honored to be part of their holiday memories year after year."
