How do I transfer music To a Moto4g phone without using Google Play? When I try to transfer music files a pop up box appears warning me that the files will be transferred but I might be unable to ply them which happens.
From what I understand, you get the default message Windows gives when you try to copy some files and it thinks your phone probably "wont" be able to play them.

Just select the "Ignore" option and go on copying anyways, the phone should be able to play the music fine.
