Thanks! Interesting feedback on the music uses. I'll post in a couple music subreddits and see what they think about it.

Great suggestion. I've been toying with the idea of leaving that open by default and switching the "Demos" button out with a "Try Now" button, so that people can actually upload a file before registering (and just have it expire after 5 minutes or something). I'll go ahead and get started on that.

Thanks again!
