The iPhone is a very powerful device, and yet it can’t play music. If you’re wondering why your iPhone doesn’t show your music library like an iPod or other MP3 player does, there are a few possible reasons. You may not have downloaded the latest update to iOS. Your iTunes folder might be empty or corrupted, which means that there’s no way for the phone to find any of your songs in order to play them back. You might also have too many folders inside full of files that take up too much memory (in which case you either delete files manually, do a full clean, or run the device’s local cleaning tool).
Stuck without help? You’re not alone. Hopefully we’re for you! Lots of people have had this problem and it’s been happening for a while now. It seems to be affecting users of the latest iOS 8 update, so you may want to roll back your system if you haven’t already updated to the newest version.
Also, the issue of “why I can’t see my music library on my iPhone” is a common problem for people who are not aware that the music app needs to be updated in order to work. You’ll need to go into your settings and tap “general” then scroll down until you find “software update.” There will be an option there called “download and install now.” Once this has been done, open up the App Store and search for the latest version of Music.
