I am trying to upload my personal music directly to the Amazon Music App. They no longer accept uploads, so I attempted to do it on my Motorola phone by going: Storage>Android>Data>com.amazon.mp3>files>music>Linkin_Park>paste. Files are in the M4a format, so I converted mine. They still will not register within the app. Song titles from the app have weird names. (i.e. ATVPDKIKX0DER_B0041RM8IK_). Is it possible for me to upload my music? Is there something embedded that I am missing? Thanks y'all.
I have pictures if that will help.
