What's happened to Radio 1?

Tweet

Over the past month or so I've noticed that Radio 1 has gone downhill. Has anybody else noticed that the playlist has suddenly dropped in quality? Songs like 'I love you better when you're naked' and tracks by the Ting Tings appear to have taken over where once there was (at least some) talent. Anyone else agree? I can't stand the Ting Tings, are there any current radio tracks that really get on your nerves?
