Wednesday saw the launch of the UK official download chart on BBC Radio 1 and in turn nudged digital music a little closer to the mainstream. It will be some time before downloads rival or even pass singles sales (itself a dying format) but the course has been set. Although Radio 1 is not necessarily the hippest radio station it knows how to target young audiences and the download chart is a recognition of the role that the Internet plays in teenagersí daily lives. One would have expected the irony to be that the people who are actually buying from the legitimate services tend to be older and firmly in Radio Two territory. However, the top two artists have distinctly younger fan bases (Westlife, Blaziní Squad) suggesting that a decent number of kids are actually opting for legal over file sharing.
