Stingray Music frequently freezes

Frequently, in the middle of playing a song on a Stingray channel, the app freezes, and I need to exit the music application and restart it. Sometimes, this fix will last for days, but more often, it only lasts for a half-an-hour or less. I have notified the Stingray support of this same issue. Can you recommend additional troubleshooting steps? Disappointed with the service.
