Broken Pygame Music Shuffler Python 3

Question

Any time I run the program, I get an error saying "pygame error: Can't open ' '". Any one know how to fix this?

Notes:
1) I am running this in VS Code

2) I am trying to pull a single music file from a folder

(Thank you to lvl 1 crook for helping me figure out how to load a single file. I appreciate it)
