I've gotten used to quickly bringing up the console (Command + alt + j on macOS Chrome, varies by platform) and running document.querySelectorAll("audio").forEach(x => x.playbackRate = 2.0) (And "video" for video tags). But it doesn't seem to work on this page because SquareSpace isn't actually adding any audio tags to the DOM (even though the mp3 URL is there). So instead you can run window.location.href = /http[^\s]+\.mp3/ig.exec(document.body.innerHTML)[0] To navigate to just the mp3 URL, and then run the playbackRate snippet in the newly-created tab to set the speed.
