^ I haven't seen anything about winter comes around again being a hybrid of other globe songs. Do you hear snippets of several songs there? I can only hear a piece of DEPARTURES, and that might just be TK compositions repeating themselves, not necessarily something he did intentionallly (though in this case it might actually well be deliberate, I know I would want to make a reference if I had composed a winter song as amazing as DEPARTURES
).
It's not on any original album, the original version is only found on the special single the song hails from and the updated TK Mix is on the 8 years ~Many Classic Moments~ best-of album.
