I'm making the long overdue switch to Android from Apple and have several questions regarding music. I'm getting either a Note 7 or S7 Edge and understand that Samsung has a great utility to transfer music - correct ? For ringtones I saw something about moving them over to the new phone and renaming them to *.mp4a - is that correct ? What is the best app to play music ? What is the best place to buy and download music ? Thank you !
