Tried listening?
You've obviously not listened to Radio 1 much. Take a look at the fab comparemyradio.com from the guys at Absolute for evidence it doesn't just dish out "Cowell sanctioned pap": http://comparemyradio.com/stations/BBC_Radio_1
I don't think You Me At Six, Gramophonedzie or Tinie Tempah (R1's top 3 played tracks over the last 30 days) would be very happy to be described as such, anyway.
And let's compare to your local Smashie and Nicey on Capital: http://comparemyradio.com/compare/BBC_Radio_1/Capital_FM - I'd say the difference is fairly marked.
6Music still needs to be saved, of course, just don't fall into the trap of denigrating Radio 1 just because you don't fall into their target audience.
