In late 2007 ThePumpkins.net and ActIV put together a cover contest featuring Zeitgeist tracks, the winning track ended up being by Somaziro which you can listen to below. Billy Corgan heard the remix version on Oct 24th and re-tweeted about it when a fan pointed it out.[audio: http://thepumpkins.net/covers/somaziro_ma_belle_(slingero_mix).mp3] [youtube http://www.youtube.com/watch?v=m1ox6l6dqrI]
