its a good app but could be better

I’m currently using this app to create a slide show video of my sister’s wedding from city hall from all the pictures and videos I took of that day so she can share, cry and laugh about that day. So far it’s letting me put together the pics I have and use some effects to write a note or two as well as have their song play in the background. However, I come to a problem where I cant lower the volume of the music so you can clearly hear them recite their nuptials so I have to cut the song to a certain point, then add the song and cut it again so it can start at the place where I left off ( where the video begins). It works great besides that. If you overlap songs it will force close and prompt an error message saying it is corrupt; its not corrupt- just move the song to prevent it from overlayying and it will work perfectly. I’ve tried other apps that won’t even open. This does eaxctly what I need.
