So I ended up making a SoundClass object called bgMusic and in the sound class object’s settings I checked the Always Play, Is UISound, and Is Music boxes.
I made sure the Apply Effects and Reverb boxes were unchecked.
Then I went to my Music.wav file and double clicked it to see the settings. Then I set the Sound Group to Music and the Sound Class to bgMusic.
Now my music plays fine while everything else echos.
