Hidden Palace Zone (Unused) - Sonic 2 OST (Custom PAL Version)

"Hidden Palace Zone (Unused) - Sonic 2 OST (Custom PAL Version)" refers to the title of a video that features a Custom PAL Version of the Hidden Palace Zone Theme from Sonic the Hedgehog 2. This is a video from the Sonic 2 OST (Custom PAL Versions) Project.

(A Custom PAL Version refers to a song that's been edited to be slowed down by 25% with no pitch change.)

Trivia:

 * Future Sonic 2 Projects would remove "(Unused)" from the "Hidden Palace Zone" portion of the title.
 * In the playlist, this video comes after the Stage Select theme. Future Sonic 2 Projects would place it after the Mystic Cave Zone theme to represent the zone's (Not the song's) placement in the Christian Whitehead Sonic 2 IOS/Android Port.
