Making its third identity change since Howard Stern left for satellite radio three years ago, WXRK in New York, better known as K-Rock, will switch to a Top 40 format, the station’s parent company, CBS Radio, announced on Monday.
Instead of the “active rock” K-Rock has been playing — mostly classic rock, with some harder-edged current rock in light rotation — the station, to be known as Now FM (92.3), will play music from acts like “Kanye West, Beyoncé, Pink, Flo Rida, Akon, Katy Perry and Justin Timberlake,” according to the announcement. The change will be made at 5 p.m. on Wednesday.
