Follow the steps below.
Test the Internet connection on your iOS device or computer.
On your iPhone, iPad, or iPod touch
If can't connect to a Wi-Fi network, you can try using cellular data:
- Go to Settings > App and iTunes Stores.
- Turn on Use Cellular Data.
You might have to pay a fee to download over a cellular network. Contact your wireless carrier for details, and learn about cellular data settings and usage.
On your computer
Open Safari or another Web browser and open a website to make sure that you're connected to the Internet.
Check the settings on your computer, iPhone, iPad, or iPod touch to make sure that iTunes Match is on.
In iTunes, turn on the iCloud Download column to see the iCloud Music Library icons. A "Available for download" icon
appears next to songs that are available in iCloud Music Library but haven't been saved to your computer and therefore won't be matched.
Take care,
