I get a few errors in all webkit browsers (error console). Also when I add a song to the group, it isn't updating on my wordpress page in webkit browsers. Only in IE.
So the group is showing in the iframe but the updated songs are not showing and in the console I see errors.
The errors are:
Unable to post message to http://w.soundcloud.com. Recipient has origin http://www.my-wordpress-page.com
When I fall back on 2.0 it's ok, but it doesn't show html5 player. I've never used this before it's my first WP project.
