I tend to listen to Radio 4 when going to - from work and during my lunch break - there's normally some excellent stuff on just after The World At One and before the dreaded Archers* When R4's not suitable I'll listen to GHR. I used to listen to Radio 2 but haven't for quite a while now as they don't seem to want me as a listener. On the rare occasions I actually put on some music of choice in the car it's normally a compilation to while away the hours.
I'll listen to music 'properly' at home but there's no real go-to musicians I've got - it'll be either whatever I've recently purchased and needs listening to, or a somewhat random choice from the Bobins record library. Yesterday evening I put on Tracey Thorn and then Boards Of Canada from the stack of ones needing listening to. There's still Sigur Rós, Lloyd Cole, Robert Palmer, Warren Zevon, The Cure, Sting, Eyeless In Gaza and a whole host of others awaiting listening..... then I can revert back to the
some thousands of CDs and vinyl in the collection

I tend not to have music on as a background distraction - I either want to listen to it properly, or not at all.
*- I use their theme music as an alarm call - it'll wake me from the deepest of slumbers and send me hurtling for the off button. Never fails
