Pop music and the Radio for non-popists

Actually, I have a question: Does the UK have anything like adult-contemporary radio? Because I can sort of imagine someone being familiar with pop songs by Colbie Caillat or Jason Mraz or Taylor Swift from the Lite FM that gets played in offices, grocery stores, laundromats, etc., and not knowing anything by Drake or Ke$ha.

BBC Radio 2 is sort of like that - they play a lot of polite singer-songwriter stuff and a tiny bit of modern r'n'b (more of the retro-styled Amy Winehouse variety as opposed to, say, Ciara). Surprisingly 'California Gurls' is on their playlist at the moment but I'd put money on it being some version with Snoop edited out.

Smooth Radio
or any local oldies station like Clyde 2 and its equivalents over the country that have the exact same playlists
