Hey @GodlessGlen I believe I found what caused the crash. Basically all of the sound cloud elements need to load into the page before you can play one. If you play one before all of the elements have loaded then your page will crash. I recommend adding a loading screen which doesn’t go away until all assets have loaded to the site.

This should keep your site from crashing
