Add a variety of transition types to your slides.
Go to Slide Sorter view using the VIEW tab ...
...or the button at the bottom right:
Then on the TRANSITIONS tab and select all your slides (CTRL+A).
On the right side of the toolbar
Here are my slides done, you can see how much time each uses for transitions.
Click and drag your song slides so you have one song slide before each list/event slide...
Go to the SLIDE SHOW tab and Set Up Slide Show.
Then set Show Type to "Browsed by individual" (this will make slides advance using the timings you've set up).
