so i buy music from many different sources on my galaxy s4. play store, and amazon mp3 store mainly. (using their respective apps). i dont like the music player for either of these 2 sources. i like the default music player for the android os. is there a way to get this default music player to view/play the music that i purchase on google play store or amazon mp3? and if not, is there a 3rd party app that will let me see all the music? including music on my sd card that i synced from my itunes? basically i want 1 music player app to be able to play music from any source i purchase from. whether it be i purchased a song on my phone from the play store of from the amazon mp3 store on my phone. after i purchase and download the song i should be able to go to a music player app and play ALL songs including these ones i just purchased. any ideas? note that i CANT see music in the google play app that i purchase on from amazon mp3.
