The true flag for useCapture is important. Browser events propagate in two phases: first, they travel down the DOM tree from the root to the target (capture phase), then they bubble up from the target back to the root (bubble phase). By listening in the capture phase, my listener fires before any event listener attached by HotAudio’s player code. Even if fermaw tried to cancel or suppress the event, he’d be too late because the capturing listener always fires first.
I was confident in that approach because you would not call multiple .play()s on the same page to lead a reverse engineer astray. Why? Because mobile devices typically speaking will pause every other player except one. If fermaw were to do that, it’d ruin the experience for mobile users even if desktop users would probably be fine. It also makes casting a bitch and a half. Even if you did manage to pepper them around, it would be fairly easily to listen in on all of them and then programmatically pick out the one with actually consistent data being piped out.
