[Gameplay] Two music in dominion overlapped each other

I recently played a game of dominion (the game link has been attached), and the game reached a point where both teams reached below 70 points. When this happens, new music plays. However, the old music (the one that plays when one team gets below 90 points) was also playing as the new music played. It sounded very weird. It would be hard to reproduce as this is the first time both teams were this close in points.

How to reproduce :

1. Start a game of dominion with anyone.
2. Allow the points on both team to drop around 70-90. 2b. Have each team take two towers and one neutral.
3. Make sure the song that is playing is the one when a team gets to 90 points (Nexus at 25% health).
4. Have the teams kill champions till both teams have 70 points (Each champion that dies causes the points to drop for the dead champ.)
5. Listing to two songs that are similar in structure, yet different, play at the same time.
