I have a Mac desktop, and had iPhones through the iPhone4, then switched to android with a Samsung GS4, and now the Note 4 (something about that number "4"....hmm).
Anyway, I used DoubleTwist, then wirelessly with Airdroid, then Kies to transfer iPhone/iTunes music to the S4, each with generally successful, not perfect, results.
With the Note 4, I decided to use Samsung's SmartSwitch directly to my Mac to get my music via my separate songs and playlists, which I kept complete owing to the fact that I also have an iPad 3 (there...not a "4"). Well, my results.....(drum-roll), also, were mixed. By this, I mean that, for some reason, I can only import a total of 1000 songs of my almost 1500 (only got 800 on the S4), and I'm not really sure why some will not translate to the android. It may have something to do with either copyright or iTune restrictions, but I'm not sure.
Have others had any better luck than I have transferring music from an Apple (iTunes) to an android platform, or have you had a similar experience? If better luck than me, any tips?
