For the controller of Radio 1, the issue of language is never far from the top of the in-tray. Long gone are the days when the station banned the song Relax by Frankie Goes to Hollywood because it talked of "coming", or when George Michael's single I Want Your Sex was only considered suitable for playing after 9pm. Nowadays the controller tussles with difficult decisions about whether to play, edit or limit to specialist late-night shows hit rap records which can repeatedly include the Ali G word along with references to "bitches" and "niggas", coded homophobia, not-so-coded misogyny, glorification of guns and routine mentions of drugs. The kids are buying them, but should they be able to hear them on the radio?
