While iTunes Match is a great way to have access to your entire music library from anywhere with an Internet connection, some users with large libraries may be overwhelmed by the sheer quantity of content displayed in the iOS Music app.
If you find that even with iTunes Match you still confine your listening to a specific set of playlists, you can easily download that content onto your device for offline listening and then go into your iOS Settings app and switch OFF the option to “Show All Music” found under iTunes & App Stores or Music.
This will limit the content displayed in the Music app to only those tracks that have actually been downloaded onto your device, providing you with a much more manageable library to navigate through.
