Someone tipped me off to a website called Videogame Music Radio. It's basically an online radio station, which plays songs from videogames.
There are no DJs or advertisements; just a program that automatically selects songs from the list of 419 videogame songs. I thought it was interesting, although there are definitely some songs I'd like to see them add to the list of rotating songs.
Anyway, I just thought I'd share it with you. I'll have to start listening to it when I'm at the office.
