A bit of old news. In browsing the Internet I came across the fact that Slacker Radio is available in Canada (It has been available in Canada since mid January). It is a service like Pandora, where you can specify a song or artist and the service will form a “radio station” with similar music.
The cool part for me is that I can use theri iPod Touch app, and via WiFi at home I can cache the radio station on my iPod and listen to it offline. I can then use it to listen to music on my walks.
Even better, at least with iOS 4 on my iPod Touch, the play/pause on my bluetooth stereo heeadset works with this app!
