how to recover my music from itune

Hello mriosad,  

Welcome to the Apple Support Communities.  

If these songs were purchased from the iTunes Store, you should be able to redownload your purchases following these instructions: Redownload music - Apple Support

All the best!

mriosad,

They may be able to be restored from a backup it was created before they became missing. Here's how: Restore your iPhone, iPad, or iPod touch from a backup. However, we want to make you aware that any backup that's restored to your device will replace anything new you've added since the date of the backup you choose to restore with.

Should you need further assistance, contact Apple Support.

Cheers!
