iTunes Match Songs Don't Appear on iPhone My iPhone 5S says it has synced with iTunes Match but some music is missing from the iPhone.  I have Show All Music turned on.  Is there some way to debug what is happening?
Just to make sure you have all the necessary settings turned on, make sure you have:


The latest version of iOS
Navigate to Settings &gt; Music &gt; 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 &gt; Music &gt; Use Mobile Data and turn it on.
