"Machines" is a song by Scottish band Biffy Clyro, from their 2007 album, Puzzle.

It was due to be released as the fourth physical single from Puzzle on 1 October 2007 but was pushed back one week and released on 8 October 2007.

The "Alternate Mix" was released on iTunes on 30 September, 1 day earlier than expected.

I wanted the album to end on a positive vibe.
