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, BeyoncĂ©, Pink, Flo Rida, Akon, Katy Perry and Justin Timberlake,” according to the announcement. The change will be made at 5 p.m. on Wednesday.
