I keep my music organized through iTunes on my MacBook Air. All my music has it's own metadata and album art and what not. I'm considering getting an Galaxy S3. Does anyone out there use iTunes for their music and sync it with their Android device? How do you do it? Do you simply do drag-and-drop? iSyncr? When doing drag-and-drop is it necessary to put the songs into Artist and Album folders or will the music player automatically be able to organize songs based on metadata? Also, do Android phone play m4a files? I remember on my Droid Incredible some m4a songs would come up with no artist or no song title when I tried to play them. THANKS!
