Hallo everyone. I have download 50 songs on google play music. All of them are in the same album. However when I was setting up google play I had chose a ugly photo for album photo. Now I want to change it or remove it back to its original music photo album. All of my songs now have the same photo. When I hear music, I open the phone and the ugly photo appears in the entire full lockscreen. I want to change the photo, is there a way to do it ? I have read that I can clear google music data, but I'm afraid this will delete all songs. Also is there any app to help me? I'm talking only for android not computer.
