BG music to continue playing when LightBox shows

I'm building an title screen for a scenario module with a button that triggers a lightbox to show biographical info on my protagonist. The title screen includes BG music, located on the timeline of the title scene, and I want the music to continue playing when the lightbox shows. However, the music stops playing when the lightbox appears, then continues when it is closed. I know this must be an easy fix, but I can't figure it out. Thanks to anyone who can help me with this.
