Even if the overall sound is mostly good, Radio 1 is in an odd place. Their listening figures continue to be under pressure (especially when you remove the 10 to 16 (or is it 17) year olds and they have an ageing daytime line-up. (Age shouldn't matter but you can't be blind to the fact not a single Weekday Radio 1 daytime DJ is under 35).
I'd be shocked if within 5 years it wasn't a very different looking station.
