Song count command

Hey there. I'm completely new to all of these variables and I can't find much information anywhere. Essentially I'm modding a music channel and they have a tradition of playing the Duck Tales theme atleast once a stream. I was hoping to make a command that essentially brings up the song count from streamersonglist whenever you type !ducktales. I followed a few tutorials but couldn't get the count to work. The tutorials themselves weren't aimed at such a specific subject so I assume that's precisely why it didn't work. I'm not entirely sure if such a thing is even possible. Any help on this would be gratefully appreciated
