Help with music player bar please..

[idk hi]

I can't get this to work on my site (neocities), could someone please fix it? I'm not very familiar with html and used this to create the music player, I copy-pasted it but it won't play.
Thank you in advance!

this is the code:
edit: it loads the yt videos so I removed it :')
if you could study the attached image instead and tell me what I should fix I'd appreciate that!
