|NO, that's NOT me!!|
I have only the one station with all kinds of artists, but you can have more than one station if you like.
It will play for quite a while and if you have not clicked on something to indicate you're still listening, it will stop playing and the screen will ask "Are you still there?" If you click yes, it'll resume playing. Otherwise, it stops. Since it is a free program, they don't want to be "playing to empty rooms".
Take a look. I think you'll like it. And, NO, I don't have any affiliation with them, just really like it.
Y'all take care
