Is it possible that the music which is skipped is DRM protected music?
Below text is part of the below linked article.
Audio or video files that are DRM protected cannot be properly shared via Bluetooth connection. The files may be transferred and even stored in a phone’s xBox Music hub, but you won’t be able to play them on the phone since the DRM protection on the file is not transferrable to a phone via Bluetooth sharing and the DRM protection will prevent the files from being played on the phone. DRM-related protections cannot be transferred or circumvented when sharing files via Bluetooth connection.
