Big news brewing on the local airwaves: The Clear Channel-owned hip-hop/R&B station KATZ 100.3 The Beat has fired all of its on-air talent and changed formats, as of 12 p.m. today.As the station's already re-designed website indicates, they will now play seasonal music. It's currently "stunting" (in industry parlance) as "Halloween 100.3 Scary Music for St. Louis." See for yourself:​Expect non-stop Christmas music (perhaps the only thing more obnoxious than Soulja Boy) after this weekend.
