The music doesn't loop. Every song ends. I recommend disabling the float function on your midi player while exploring the near one hundred pages here. There's music on almost all of them, specifically selected to accompany the content of the page. Carrying the piece from the last page to the next defeats the purpose and midi files can stack up and overwhelm your browser.
All midis are original and used with the composers' permission.
Information about the great music and art is on the Roll Credits page. The award submission page is in the Awarded section. Links and Style and Content both contain information for writers. Style and Content contains non-fiction articles and opinions. I recommend visiting that section if you're unfamiliar with the terms polyamory or slash.
