On The Dark Side by John Cafferty & the Beaver Brown Band. This was written for Eddie and the Cruisers, a 1983 movie about a New Jersey bar band. In the film, the song becomes the band's big hit and leads to a second album and a conflict with their record company. Kenny Vance was the music supervisor on Eddie and the Cruisers.
The longest solid Dream Theater song is Octavarium (23:59). The DT song In the Presence of Enemies is over 26 minutes long, but is broken into 2 parts on the studio album. A Change of Seasons is also quite long, at 23:06. The progressive trash death metal band Meshuggah has the song I (21:00) and Catch-33 (47:09).
