Hi Steve,
I’ve often fallen asleep to Drone Zone and like Secret Agent as well. I haven’t listened to Groove Salad but recommend Jazz Radio - Groove.
After 1.2 is released we will have to get some kind of Internet Radio swap meet thread going so that all the better quality streams can be gathered together in one spot for editing into station entries.
Edit: And here is a swap meet thread for us all to exchange favourite URLs.
