If you have the icloud on both your iPhone and computer you should be able to get your music through it

A good iPhone transfer can help you. Like Syncios iPhone Transfer, which can backup all the audio files including music, ringtone, audiobooks from iPod/iPhone/iPad to PC which iTunes does not allow you to do.
You can also add local music files from your computer to iPod/iPhone/iPad, delete or export audio files from iPod/iPhone/iPad, add playlist on iPod/iPhone/iPad and etc.
