Really want to purchase an Iphone 6 as I've fallen in love with the hardware, after using a friends for a couple days I love the aesthetics, ease of use, camera & screen (and second hand price tag) however I've always relied heavily on the ability to cast from my phone to tv using chromecast, I download music via tubemate as this is how I've built my music library and don't want to start fresh, on the subject can I transfer my music library from my android phone to Iphone
