I think the original was written by Interphace of Andromeda. Don't mean to steal any credit of course, but I always like this remake I did 9 years ago. Some samples are from Andreas Viklund.

Hmm, there are a few similarities but it seems to be rather different from the original tune. Not that this would be a bad thing, it's still a nice track. :)
