DJ Sona Music Looping

I've encountered a weird bug where DJ Sona's music loops the same section of one of her tracks endlessly and never progresses to other parts of the track. The best way to describe it is constantly building but never 'dropping'.

Steps to reproduce: Begin a game. Switch to "Ethereal". Progress to level six. After using your Ultimate at that level, return to base and switch tracks with /toggle. At that point, the music should be looping a section from the "Kinetic" track. If you switch, "Concussive" begins looping. The bug seems more pronounced in games with other players, and seems to get worse the more you die, in the game linked below: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1752901335/200173725?tab=overview It progressed to the point where about 0:17-0:34 of "Kinetic" as seen in this Youtube link, looped endlesssly without ever progressing past about 0:34 before returning to 0:17. The results in custom games seem a bit different based on what I tested, starting out in Kinetic and remaining in that state until level six didn't seem to affect the skin in the same way, but there did seem to be layers of the song missing at that point. Dying in "Concussive" in a custom game caused a section of the track to loop endlessly until respawn (not sure if that's intended though).

Thank you.
