In the UK, what's the difference between Radio 1 and Radio 2?

Question

I've got a few songs from Biffy Clyro (great band there) that happen to be ripped from the radio, and in the tracks, the radio call letters are mentioned.

Unlike in America where we use 'K' and 'W' plus a bunch of scrambled letters, the UK seems to have stations called Radio 1 and Radio 2.

Can someone explain what these are, how many other stations there are, and what the difference is between the two?

Answer 1
