For those that do not know, Subsonic Radio has also been hosting a 2nd scheduled stream at 64k for quite a while now. If you need to take a break from the current track on the Request stream you don't need to leave Subsonic Radio. Just click on the Scheduled stream in the left side navigation!
Here's the current schedule, all times are based on PST.

Personally, my two favorite schedules are Yesterland on Tuesdays and a walk through the lands on Thursdays.
