Chosen Solution

I had used my old computer for seven years and a few days ago it got Hard Drive crash accidentally. I couldn’t express how annoying and painful due to this case because I had my irreplaceable songs imported from CDs and download from the Internet in my iTunes Library lost. The only one thing I was grateful was that some music was stored in my iPhone 6. Now I have to buy a new computer and install a totally new iTunes on my new computer. Is there any way to recover the iTunes Library with my iPhone? Any hope?

Whatever was stored on your iTunes, should be identical to what you download, after you sign in. There’s also the cloud. Which you can download to your phone, and then backup to your iTunes
