None of the music is working. Everytime I buy a song, and download it, it doesn't upload to the Samsung music app. It says I have no music on my phone, but that's not true. I wish they had a scanner button, so I can scan all songs, and then upload it after it scans your device to get all your music on it, onto the app. I think the app would work a lot better, if they added this feature here... But until that happens, this app pretty much sucks now. Which is a real shame, cz I used to love it.
