A. Restart the app to see if that resolves playback issues. Double-tap the home button (or swipe up from the bottom on newer iPhones) to view open apps, then swipe up on HotNewHipHop to close it. Reopen the app and try playing music again.

B. Clear the app's cache if possible. Go to the app settings and look for an option to clear cache or data. This can help resolve glitches by refreshing the app's stored data.
