How to download songs for my iPhone on a different itunes on a computer?

I don't want any of my current songs to be deleted. How can I change computers/iTunes and just add new music on?

ITunes is annoying like that. The best thing to do is download CopyTrans Manager and use that to put your music onto your iPhone.
It's been a while since I used iTunes but there's an option in the store tab that says "Authorize this computer", maybe that could help.

  • Two different computers, two different iTunes.can I use the same Apple ID? I have iTunes on my computer that I use for my iPhone, and my mon just got an iPod Touch and wants me to fill it for her. I'm going to use her computer to do this, which currently does not have iTunes. Once I download iTunes, can I use my own Apple ID to download songs and apps onto her iPod? Is it possible to do that without disturbing what's on my phone, or do I have to make a whole new iTunes account for her?
  • Transfer iTunes library to a different account on the same computer? My mum hates that my siblings and I put all of our music in her iTunes library because we don't have a computer of our own. I just created a new account on her computer (MacBook Pro) for us, but I can't seem to transfer our songs to that account. Every time I try to transfer the songs from my iPhone (same songs as on my mum's iTunes), it says that they've been transferred but the library stays empty. Any suggestions?
  • ITunes won't download all the songs to my iphone 6s after transffering my list of songs from my old macbook to my PC I transferred my list of songs from my old Macbook to my PC with iTunes. For some reason, iTunes won't download ALL the songs to my iPhone 6s from my PC. For example if I want to download a whole album it will only download few songs from that album. Anyone know how to fix this problem? I also noticed how long it takes to download just few songs from my PC to my iphone 6s which is really frustrating.
