Hi @Lcmarincek,
Welcome to the Roku Community!
We understand you're having a problem with the Apple Music app or channel.
When removing a channel from your Roku device, it's important to restart the device before adding the channel back again, specifically in that order.
If the issue persists on one channel after attempting the troubleshooting steps and videos from other channels play fine, contact the channel provider's customer support team to report the issue and get help. The channel developers themselves maintain channels on Roku. In this case, an issue within that specific channel likely needs to be addressed with an update from them.
Please let us know if there is anything else we can do to help you.
All the best,
John
