I don't really like reading articles in the guardian, let alone linking to them, but I think this raises some very good points, that seem to ride against the consensus on this here website; specifically about niche programming. Does 6music convert people to new and interesting music? Or does it just appeal to people who would listen to it anyway? Idk.
(I personally STILL listen to Radio 1 a lot more than 6music, by the way)
