Every time Evan tries to fix the past, the future becomes even more messed up than it was before - he's stuck in a vicious circle - or cycle. Staind's "Break The Cycle" syncs so well with "The Butterfly Effect", it's as if the two were created to go together. If you have a software player such as PowerDVD you can view both the original movie subtitles and the song lyrics subtitles at the same time. By selecting the optional second soundtrack, you can take the sync experience to a whole new level with a mix of the movie audio and CD. Hope you like it!
