In the findContainer method, that selector and loop is going to be quite expensive, since there could be a lot of divs on the page. This would do the same thing but muuuuch faster, no?

document.getElementsByClassName('sound playing')

Spadgos: I just updated it, considering class name differs when not on main user pages("sound single playing"), this version should be quicker and more versatile(note: I didn't see your comment until I updated). It's 5:13am here so I'll be done with this for tonight, but I'll take a look at improving speeds when I've got more brain to me. There's also an issue with the "load" event at the bottom not firing when opening a link in a new tab without focusing it, so that'll need to be changed.

fixed chrome/latest clientside api changesI(they moved to webpack)

@dwent Sorry for off-topic, but can you help make this Soundcloud: Sort comments by timestamp userscript fetch all the comments itself when the user clicks Sort by timestamp? Currently it relies on the user scrolling down manually and then clicking the sort button.

I set up an XHR/fetch breakpoint for the /comments requests that occur when you scroll. I looked around in the stack but I admit I have 0 clue about how I can call the necessary methods myself, or whether that is even possible.

Thanks in advance!
