Some of Australia’s biggest names in music, and the radio stations that play their songs, are at loggerheads over a push for radio stations to pay artists more when their songs are played. Tones and I and John Farnham are among a 500-strong group of Australian artists who have signed a letter calling to scrap a decades-old rule cap on the sound recording fees that radio stations pay to play their songs. Commercial radio is warning scrapping the cap could lead to stations shutting down.
