Website player problem(s)

So ummm, the reason why i use this old as fuck javascript played called Wimpy player is because of these reasons
  • I wanted a HTML5/Javascript player that was reminiscent of the old Adobe Flash ones that for example were featured in DevinatArt pages way back in the day
  • I wasn't a fan of how before that my website's music sections were nothing but a long list of link spam
  • I wanted something that could fit nicely within my website and also was at least kinda close to oldskool design trends, as i feel like flat design won't do my site justice

A significant problem this player has

I've been using this player on my site for months and it looks really cool, it fits the vibe of what i want my site to be and it also has options to adapt itself via responsive CSS so it's usable in mobile screens.
I've found one big problem though:

How it fails when it comes to accessibility

It absolutely fails to meet the WCAG standards when it comes to keyboard accessibility, meaning that people who use a screen reader to navigate this site will find it impossible to use this portion of my website :c.

I don't like how this media player is functionally ableist, however every other modern working javascript player I've found is designed via flat design standards that don't fit at all and i don't really know how to modify them due to my lack of experience in Javascript and customizing those parts of the web.
I wonder how i can fix this. Also the Wimpy Player is freeware, not FOSS, meaning that you cannot modify it's code without explicit approval from it's creators along with other legal bullshit.

I will eventually think of doing something to remedy this, maybe modifying a modern looking media player to make it look more like the one I have now I guess when I know a lot more of what I'm doing.
