Do you really have to sync your iPhone to iTunes anymore?

I have an iPhone 6 by the way

There's a 3rd party app you can use which is much faster but does the same job as iTunes.

You don't have to but it is recommended

Same phone as you. I will NOT sync - I move my music manually, since it is things I usually rip from big (about 3,500) CD collection. Frankly, it is easier to put music on my mp3 player - but if I really want something on my phone, they do NOT amke it easy! I usually make a play list, and then manually send it to my phone from iTunes. Really - having 2 devices is So much easier. We're bot career professional classical musicians since 1973, and have owned and used every kind of music media there's - and the phone is the clumsiest if you want to transfer what yo ALREADY own.
