iTunes Match Songs Don't Appear on iPhone
Just to make sure you have all the necessary settings turned on, make sure you have:
- The latest version of iOS
- Navigate to
Settings > Music > iCloud Music Library
and turn it on;
Also, make sure you are connected to a WiFi network (the default behaviour of Music app is to only allow music downloads through WiFi). If you don't have a WiFI connection, enable Data Downloads navigating to Settings > Music > Use Mobile Data
and turn it on.
