Q: how to transfer iPhone songs to macbook pro without removing the songs from iPhone?

Greetings anaind,

Welcome to the Apple Support Communities!

I understand that you would like to transfer music from your iPhone to your iTunes library on your MacBook Pro. If the songs on your iPhone were purchased from the iTunes Store, you can transfer those purchases using the instructions located in the attached article. 

Re-download or transfer your iTunes Store purchases from an iPhone, iPad or iPod to a computer - Apple Support

Cheers,

Joe
