Playing music like the Rolling Stones’ “Street Fighting Man” and hip-hop tracks with heavy bass lines are most likely to trigger violence in pubs and nightclubs, according to an academic study funded by the NHS. But tracks by artistes like Robbie Williams or the Sonny and Cher hit “I Got You Babe” can calm drunken revellers and defuse potential disputes. Researchers from Glasgow University monitored the play lists and outbreaks of fighting at eight city centre pubs and bars. They discovered that loud rock and rap music encouraged customers to drink more and increased loutish behaviour that could spill over into violence. A spokesman for JD Wetherspoon said the chain already avoided playing R&B and rap music after its own research showed the bass line can be “quite aggressive and potentially cause problems”.
