The 2008 BCI "Irish" music crisis erupted in Ireland in March 2008 when it emerged that certain bands and musicians who had recorded material in Ireland were classified by the BCI as "Irish" music for radio airplay. Independent radio stations regulated by the BCI have an obligation to play agreed levels – in most cases 30% – of Irish music. Concern mounted that genuine Irish music recorded in Ireland by Irish musicians was being overlooked in favour of mainstream international trends.
