HTML Dark Music Profile Code's Comments

I love this so much! Very beginner friendly! Decided to not add music, but the rest looks amazing

Is there a way I can change the audio? If I can can you tell me bc I want a different song to fit the aesthetic :

For some reason i can't access the actual code 

Awesome code, love the design!

 And putting an invert filter on the player is so smart, I wanted a dark one for a while now and wasn´t thinking of that method. xD
