"..there is always soma, delicious soma, half a gramme for a half-holiday, a gramme for a week-end, two grammes for a trip to the gorgeous East, three for a dark eternity on the moon..."
If you like drone-ish type music to work to, there's a variety on SomaFM. Or eight flavors of EDM, or even Americana. I usually tune in when I'm looking for "atmosphere", rather than a particular music I'm going to pay a lot of attention to.
Their Xmas in Frisko station is so great for this time of year.
I like getting festive but I don't like the majority of Christmas music. They have a quirky and sometimes offensive collection of holiday music for that station. It's great!
