This is very fun, Sonic! The beat and harmonies are great and they make me wanna dance, just like the original. It can be really tough to pick just the right instrument for that vocal line, can't it? I think your choice here is pretty good; nice and synthy. Well done!
Thanks! I actually left the synth for the vocal part from my MegaDrive / Genesis remake of the song. You can hear that here: http://www.youtube.com/watch?v=t7yWKEwrDOM
