Never mind. When CBS first implemented timeouts, they didn't have an explanation on their website. Now they do.
In an effort to control streaming fees paid to agencies that represent artists, record labels & publishers many companies that provide Internet music services, including CBS Radio, have activated time-out features. In our case, between the hours of 10p - 5a, the CBS Radio player will stop streaming (time-out) after two hours of inactivity. What this means is, if you launch the player, minimize it then leave it untouched for two hours the stream will stop until you either mouse over it or click the start button to resume streaming.
While you may be an active listener, there are thousands who are not, and CBS Radio is held accountable for every song played while the player is on whether somebody is actually listening to it or not. We've set the time-out feature to function outside of normal peak listening hours to pose as little inconvenience on our active users as possible.
That's reasonable. I didn't even realize there was a window. I suppose it won't be too much of a hardship to hit Play again in the morning after it has timed out. /img/vbsmilies/htf/smile.gif
