Early OST#

Title	Early	Final	Description
Discovery - Title Screen			This theme has multiple differences from the final release, including less reverb on the lead synthesizer, audio being all-around more compressed than the final version, and a smaller amount of instruments/sounds compared to the final.
Comfort Zone - Main Menu			Same as with the Title Screen: less reverb and instruments, and more compression.
Green Hill Zone Act 1			Less reverb, less instruments, and more compression. Noticing a pattern?
Lights, Camera, Action! - Studiopolis Zone Act 1			Same as with the other tracks. The intro and the pre-refrain especially sound pretty rough compared to the final. The song fades out at the end, whereas the final version ends with a sting.
Flying Battery Zone Act 1			Missing instruments from the final. Also, the intro from the Sonic & Knuckles version of Act 2's theme is played at the start.
Tabloid Jargon - Press Garden Zone Act 1¹			Was completely redone in final. Has more of a traditional Japanese feel compared to the final's industrial sound. This appears to be from after the zone was changed from a garden to printing factory, as some quiet machinery sounds can be heard in the song.
Rogues Gallery - Mirage Saloon Zone Act 2			Same as with the Title Screen, Stage Select, Green Hill & Studiopoils.
Stage Clear²			A unique composition that features the game's main leitmotif. The final game instead remixes the stage clear theme from Sonic the Hedgehog 3.
Credits³			Was completely redone in final. The final is more energetic compared to the early version's more relaxed feel.
