Try 6Music.
There's never an excuse to be bored of music radio, especially if you have a digital one. Bit of Radio 1, Radio 2, 6 Music, XFM, Chill FM for non-stop Royksop, and throw in just a touch of commercial radio for the same tunes they've been playing for the last 20 years (it's only diverse if you weren't sentient in 1986. Tears For Fears again, anyone?).
