can anyone tell me why I can't get my ringtones on my S4? maybe it is the file? it is a m4.r file and in my itunes?I can click and drag other files to my android but not these. thanks

There may be a DRM limitation on the file.
Is it a clip from a song? If so, and the song plays on your S4, try Myxer on Play. That can take a cut from a song and use that as a ringtone.
