For the past couple months, the Soundcloud API was not playing nice with this site, so I turned it off.
I have tested again and it doesn't seem to be hanging pages.
If the page hanging and site suffer again, I am going to remove it. There was a known problem with some sites and other sites that used Soundcloud's API, looks like they fixed it.
So you can use the Soundcloud field again.
NOTE: Most of you that DID enter a link into it, the player should automajically show up now, the site was still saving that data.
