I know I shouldn't find this odd... but I do.

Radio 4 always goes with the SERIOUS politics first
Radio 6 always goes with the TRAGIC MURDER/Celebrity death first
Radio 2 and Five live somewhere inbetween.
Radio 1 probably zane lowes drum n bass fashion tips, dunno.

I've listened to news broadcasts on Radios 4, 6 and 2 within an hour before, and they've all had different lead stories.

If I did any research into this I'm sure I could come up with some cutting-edge sociological theories. But I can't be bothered. Someone else do it for me please?
