For music:

http://trancearoundtheworld.com (2 hour + streamed sets)

http://pandora.com (paid so theres no commercial distractions)

http://thesixtyone.com (streamed songs you don't know about)

http://mugasha.com (good quality well-known streamed sets for free)

Love the streamed sets because they don't interrupt your workflow. It's like being at a coding dance party; for hours.
