How to move MP3 files into my music library on my iPhone?

ITunes is no longer supported on my computer and I can't transfer music to my new iPhone through the normal iTunes route. Are there any other ways I can move MP3 files from my computer to my Apple Music app on my iPhone?

There are a few programs that can do this, so if you have a look on Download.com you can get a good idea of what's out there. Remember though to always check what other sites say about such software, and always scan anything you download before using it!

I've recently had to transfer a couple of my partners parents CDs to their iPod Minis and used the program CopyTrans to manage the transfer. While it's not completely painless it's not bad!
