but every internet radio station i listened to had way too many ads, sometimes took forever to stream and contantly stopped to seek confirmation that you were still listening 
itunes has a radio function, where it has all the genres and about 20 different radio stations to choose from in each. It streams perfectly and constantly and has NO ADS! yay. It's right there on the player, tucked away on the left hand menu.
I leave it playing in the background while i do my stretches or yoga.
Happy (FREE) listening everyone!
