Bleah - Fart FM
My missis used to listen to those two annoying twats until I asked her to either change stations or switch the damn thing off. Not only are those two enough to make you take a hammer to the radio, the station itself seems to have a library of around 100 songs which they constantly recycle. Over a year since I stopped having the thing inflicted on me, I went somewhere that was playing Heart and, surprise surprise, they were playing the same bleedin' songs as when I last heard 'em.
Oh, and they're sponsored by TalkTalk, if you really need another reason to dislike them.
