Welcome, and thanks for posting here in the Roku Community, @LaFlegere.
We understand that you're experiencing a playback issue with your music streaming apps on your Roku, and we'd like to help you out so you'll get back up and running.
Have you tried rebooting your Router to see if that makes any difference? If not, try unplugging your Router for a few seconds and plug it back in. Also, to isolate the issue even further, try connecting your Roku to an alternative internet connection such as a Mobile Hotspot.
