Compatibility with Spotify SDK?

[mcgingras]

Has anyone gotten the extension to work with a page using the Spotify SDK? (Not open.spotify.com) I can't seem to find any audio or video elements on the page when using the SDK like the ones that are available on open.spotify.com

It injects an iframe but the iframe is empty aside from a minified JS file that is hard to understand, and a google analytics tracking tag. Is it even possible to play audio without a HTMLMediaElement on the page?

I'd like to be able to slow down tracks on a site I'm writing that makes use of the Spotify SDK, but so far I'm having quite a bit of trouble figuring out where to find where the tracks are actually playing. This chrome extension was the closest thing I could find.
