Why do songs play when the battery charger is hooked up and when full?

[AC Question]

Song plays when battery charger hooked up and when full.

Galaxy S4 phone. When I plug in charger, when battery full, when I hang up a call and on other instances a song will play. It's an old ring tone that I cant even find to delete. How can I get rid of it?

Greetings and welcome to Android Central!

Is your ringtone somehow stored on your SD memory card?
