So, I have four levels, and I want the music to be different for each level. I'm using a trigger at the beginning of each level, so when you hit it, the music is supposed to change and stop the previous level's music at the same time. Instead, what is happening is that the music from all the previous levels (except Menu music) and that levels music are playing at the exact same time and it sounds really weird. Here is the link to the game I am having trouble with: http://flowlab.io/game/view/952637
Please help me solve this problem so I can finish this game's 2.0 update.
