Thanks alot for that youtube link. It's exactly what I wanted to see.
Funny thing is I was thinking of doing something like this myself, but my TV Tuner card thing proved to be difficult when it came to the video recording. And anyway, if I was to get it to work, I was planning to to Emerald Hill and Sky Chase zone with those exact same two songs.
I also like the remix for the Casino zone and Hidden Palace.
And thanks for letting me know about Sonic 1
