Samsung Galaxy Note 2 - music players on galaxy note 2 choppy

[bishop793]

My galaxy note 2 has started giving choppy playback and sometimes shuts off completely. It does it on the stock player, Google play and winamp. Playback also seems to gets interrupted when I press the home key and press the side button to get it in and out of sleep mode. Restarting doesnt seem to help. Its as if something is running in the background thats draining some key resources. Any advice? Thanks
