Struggling with "Delay Between Songs"

Hi,

MY GOAL
I don't want the playlist for my background music to simply keep playing songs without interruptions => I would like to have some quiet time in-between each song, where nothing happens.

MY ATTEMPT
Therefore, I tried to attach the "Delay Between Songs" script to my playlist. It seemed like it would wait between X (Min Time to Wait) and Y (Max Time to Wait) seconds before playing the next song.
However, this caused each music in the playlist to skip after a few seconds already, making things worse.

Any advice on how I should proceed in order to achieve my goal here ?

Thanks a lot !
