Great service, terrible app

Uploading my own music is the primary reason I chose this app over others, but the app has a lot of issues. Sometimes if I pause, I cant hit play until I skip a song and go back. Also, if I skip a song, sometimes the next song wont actually play and the solution is the same. This is downloaded music so there should be no loading time. This issue has persisted over several updates.
