I only ever listen to radio one when I get my hair cut - my barber has it on - it is dire - full of garbage wannabie musicians. Since they changed their policy and started trying to be a teenager's station listenership nosedived and now radio two has more listeners (and plays better music).
The best (bar none) station at the moment is Radio Caroline it's not on the airwaves anymore but it's on line and on the sky digital platform.
There is a lot of good new music around but it is submerged under the sea of dumbed down dross. I blame reality TV, the rise of the "DJ" as a performer and "Rap" all of which gives people with no talent whatsoever the opportunity to pretend they are musicians, perform and record thus thrusting their inanity on to the rest of us.
