Error with .play()

Hi guys,
As I found help here before would like to ask if any of you can help me with the following issue.

I’ve created a audio player app, which was working well and I decided to practice my DOM skills and try to create the markup from js. Everything seems to be on its place, and I think my code went too messy and also have a error The play() request was interrupted by a new load request.
I saw few articles about the error but couldn’t manage to fix it on my own. Would be really appreciated if you can help me with it, also give me a tip how I can form my code to look better and work better of course.

Thanks a lot! Here is my repo on github
