Super Mario Galaxy 2
In Super Mario Galaxy 2, a more unsettling remix plays, with the same chord progression for the first 18 seconds, but the last 6 seconds have a D minor chord instead of an F#7. It plays during Daredevil Comet missions that lead to a boss fight for the entire level prior to that fight and when Mario approaches Bowser's Galaxy Generator.
