Using script in Logitech Media Server

[alnames]

I started using this script in LMS to replace the no longer supported Official SiriusXM stream. It works well until I change stations. The new station plays for a while then stops. The python terminal output shows a lot of 403 Forbidden errors when I select a different station and appears to be attempting to stream both the old and new selection. I'm not very familiar with python but shouldn't the previous stream be terminated in favor of the new one?
