One reason I haven't used itunes in years, and don't use iOS, is that I have a huge collection of mp3s. It's almost all of music which I bought and burned off CDs over decades, and it's become just stupidly difficult to organize your own mp3 collection via Apple's players. Even back in the ipod days, you could put your mp3s on an ipod but you needed piracy ware to rip them back off. I can easily see this leading to people like me getting piracy notices and having to explain that no, I bought this music, since we're now in a world where not that many people have their own unlocked music collection anymore.
