I am coming from a Note 2, with a short time with a G3. I also have the Note 10.1. My question or questions have to deal with the stock music player or actually all music players I have tried on my Note 4. All my music is stored on my SD card. In the "my music" file. On this phone not all my music shows up in the music player. Such as I will pull up an Artist and only one or maybe two albums will be there. I can go into my SD card and open the file, and all the albums will be there. I can place my SD card back into my G3 or my 10.1 and all shows and works fine. Also it splits songs when I look them up under artist.
