No music playing as DJ Sona?

Hey so, um, when I play as DJ Sona , I get no music. All of the other in game sounds work fine, just no music. Also when I try to toggle to a different track (trying to see if any other track works) nothing happens. Everything worked fine when it was first launched but after a patch I assume, I get no music. It's kind of an expensive skin that my boyfriend bought me, so I'd just like it to work. :( Pls help <3
