Reasons Downloads Are Interrupted on iPhone
An interruption during an iTunes Store download can happen for various reasons, including:
The iPhone drops the internet connection: A malfunctioning internet connection is the most likely reason why the song fails to download correctly. You may end up with a partial song or nothing at all. An issue with the iTunes Store servers: Apple servers are rarely down, but it can happen. A problem with a server can terminate the connection to the iTunes Store. An unexpected iOS restart: If the iPhone restarts during a download, the song cannot fully download. The internet connection is slow or the Wi-Fi router has problems: If your internet connection slows down or your Wi-Fi router loses its sync during a song download, the result may be a failed song download.
How to Resume a Failed Song Download on the iPhone
To restart a failed song download on your iPhone: If these steps don’t fix the download problem, restart the iPhone and repeat the process. If the failed download doesn’t appear in the list or if you can’t fix the broken download, either report the issue to Apple in person at an Apple Store or use iTunes (or the Music app) on a computer.
Use iTunes on a Computer to Fix a Download
If you sync your iPhone with iTunes on a computer, fix an interrupted download by using the iTunes software to sync the song to the iPhone. Open iTunes on your computer, select Music from the menu in the upper-left corner, then select Store from the options at the top of the screen. Then, go to the menu bar, select Account, and choose Check for Available Downloads. If there are no available downloads, check your account details in iTunes in macOS Mojave (10.14) or earlier to confirm you purchased the song and to request support.
