Multiple SoundCloud Track Into 1 Script

I embed this script for my WordPress page ->
angora.me/music

But after I checked on Varvy, Pingdom, GTmetrix, etc,
this script is very bloated and make my web very slow.

How to combine these multiple track into 1 script?
I want embed multiple track but I don't want bloated.

Note :
I tried SoundCloud shortcode for WordPress but it doesn't work.

Here is the script ->
