Stepmania Online

I've been trying to find songs at http://stepmaniaonline.net/index.php?page=downloads and have been able to download packs from that site. I know individual downloads aren't supported, but was wondering how to find the pack that individual songs are in. Whenever I click on an individual song link, the line "Packs included in:" is blank. Any help would be greatly appreciated!

Use: http://search.stepmaniaonline.net/pack/search?q=song

replace the url part "song" with whatever song you are looking for.

Thanks!
