Default [Q] music starts while plug in usb!?

Hello Fans,

since yesterday i have a very strange problem: everytime, when i plug in an usb-cable (pc or charge) in my note 3, the phone starts to play the samsung song "over the horizon". The only way to stop it, is a restart.

Has anyone a soloution ... please?!

-> O.K. i found it: It's GravityBox [KK] vers. 3.3.2!
Went back to an older version and it's o.k.
