* The music for Sunset Park Act 3. [[http://www.youtube.com/watch?v=dot0iGpUL5I Listen.]]
** The actual transition into Act 3 itself. Sonic or Tails hops onto a strange platform and flips the end-of-level sign, only to find the whole thing is ''actually a train''. Cue the Act 3 BGM as they run up to the front of the train.
* Honestly, the entire soundtrack is excellent – we expect no less from this franchise. Some more examples:
** The under-appreciated – due to, well, listen to the entry above – music for [[http://youtu.be/_dy70N9gX8A Sunset Park Acts 1 & 2.]]
** [[http://youtu.be/q8Q7lAxQ4z8 Turquoise Hill Zone.]]
** [[http://youtu.be/QFHmEbdaWaY Meta Junglira Zone.]]
** [[http://youtu.be/Oy7OXaQFmeI Robotnik Winter Zone.]]
** [[http://youtu.be/1QUlGNU72Lk Atomic Destroyer.]] An unusual example of ''Sonic'' music being intentionally discordant and frantic.
** [[http://youtu.be/wGIcDsPoqyI The airplane segment.]] Sadly, the constant humming of the Tornado's engine drowns out a lot of this one in-game. Luckily, the game has a sound test (and people who care enough to upload the BGM).
