I'm a big fan of Radio io 80's. The io network has some amazing stations, with acoustic, edgy, 90's, ambient and more. The link here is for the 80's station but there's a row of links at the top of the page that will take you to all of their stations.

The reason I love this 80's station more than others is because they play tracks that never get heard on other stations. I mean, how many times can you hear Mickey and Hungry Like The Wolf, seriously. They will play album cuts from your favorite artists, remixes of well known songs, live versions, new songs by classice 80's artists and covers. He'll even play covers of classic 80's songs done by independant bands. It's a really well done show.
