So I've had a station (mac desktop) for a long time, many up and down votes. worked fine for a long time then out of the blue it's changed to a kind of music I never selected and don't have anywhere on any of my playlists. It went from Brian Eno ambient type music to rockabilly. Couldn't be more different. How the heck does that happen? So i thumb-downed a whole bunch and my entire station's songlist disappeared. Say what?
