Radio is absolutely terrible I've noticed. My AUX cable broke last week so I've been listening a lot for the first time in ages. Radio 1 is mainly pretentious and hosted by idiots, and Free Radio is a complete joke. How anyone listens to that I'll never know.
Annie Mac is definitely overrated in my opinion, the music she plays isn't very good, and all you have to do is look at B.Traits and a few other of the DJ's that host the new/dance music type shows to she that in comparison to them she's quite weak. She has quite big status at Radio 1, but I really don't rate her, or the music she plays at all.
