Tunneled starts off with a catchy bass line then into a dark opus signifying the stress of being chased through a dark tunnel with the only option of going forward as fast as possible.  As the song progresses a short interlude breaks in then it bounces back into the "chase" theme given from the get-go.  The song has many different parts, and pieces of it could be used for various breaks in videos.  Being a fast-paced action song, it would do well in conjunction with any theme stressing urgency with dark overtones.
