It'd be an interesting remix to start with the theme while you're on the plane, then Knuckles theme [as he's ganking your emeralds], then Briefly the Act 1 theme for Angel island followed by a remix of the special stage, then back to the act one theme. Special stage again, then Act 1 theme again, followed up with the miniboss theme. A remix of the end stage fanfare.
Then a remix of act 2 [with that lovely xylophone], the special stage remixing again [very shortly in btw], more of act 2, another special stage, more of act two, then the robotnik fight theme remixed, followed by a fanfare.
So, essentially it'd be a remix of someone playing through Angel island from start to finish as if they found and collect all the 4 emeralds located within angel island [there are only four right?].
