Recommend free online music radio for work

Music helps me focus on my work and not get distracted by other things. I'm looking for an online radio with calm music, does anyone have any recommendations? Am I the only one that needs music for work? :)

You're definitely not alone :) Music really helps you focus and drown out all the distractions. Do you wear headphones while working, too? I listen to radio online at the Kuasark com, there's a huge selection of free, ad-free radio stations. There's even a special section called Music for Work with quiet and background tracks. I also like Thegooshradio Deep House on the same site . What kind of music do you like to listen to while you work?
