Please use the "!?" button and then the "Report broken stream" link in
the app's now playing screen to let me know about broken streams and
I'll respond when it's fixed, if possible. That way I know exactly
what stream your talking about, what type of network you're using etc.
and can more easily fix the issue.
You can also report them using this form:
