I think I am in the minority here, but I am thrilled about this. Long overdue. I have iPhone 6, and I absolutely HATE using it for music. I travel quite a bit, and when I forgot my iPod one time, I used my phone - and found that by the time I knew it, my phone died from using it for hours on the plane, and I had no way to charge it soon after I landed, thus I had no phone. I was always one to keep my music separate from my phone. I have both a touch, and a nano - but just want something newer. I'll be getting a new touch for sure.
I surely can't be the only one that hates using my phone for a music player.
