I believe there is. A radio is different than ian nternet stream. A radio sigmal doesn't affect anything; it is there for the taking, but an internet stream uses bandwidth; not just yours but the senders, too. Amazon nor Tunein want to waste bandwidth if a stream is being sent to an empty house, for example. So most streaming services have a 5 hour or so time limit to ensure this is not happening. If this happens and one wants to continue the stream, one needs to start it again.
