Multiple Music Files Playing at Once

This was working fine December 1st. I would click on the day, the lightbox showed an image, the lyrics to the carol, and the music file for the carol would play. Now the image and text looks right, but multiple carol files seem to be playing at once now. I’ve looked where I’ve embedded the music files, and there just seems to be one song embedded per day. My versions are current, and I haven’t made any changes to the site since the 1st.
