I'd Appreciate a Bit of Help (A giveaway with a musical catch)

So, recently, I discovered this artist. He goes by the name of Silva Hound.

How I found him? The incredibly large MLP fan music archive. But that isn't the important part.

The important part is that most of the time, he remixed old songs into house songs based on MLP characters.

But his first 6 or so albums have been mostly wiped off of the Internet (I have no idea why).

One of these albums is named "The Royal Wedding EP". I listened to one of the songs, and found it incredibly familiar.

It bothers me dearly that I cannot figure out for the life of me what this is a remix of.

And I figured, hey, can't SG help? My first thought- no. But then I remembered. I have incentives!

I bought Gravi from the Alpha Fundle Bundle, and Eleusis from the Groupees Be Mine 8. I don't yet have the Steam keys for those, but I figure I will soon. (I can prove both of these through screenshots.)

So, to whoever can find/tells me the original song will be promised one of those games (of their choice).

However, if the original is not the one I know,(and I don't believe it is) if someone finds the version/other remix that I know, I will give them either one of those keys or something from my inventory.

I beg of anyone who is trying this who is not a brony to ignore the vocals and audio cuts within the song.

The song is here, and the part that I recognize is from around 1:05 onwards, so this link will go straight to 1:05.

Don't bother looking at his Bandcamp. I already tried.

And one tip, the only thing I can remember about the version I know- it's incredibly repetitive. Even more so than this one.

I was thinking about making a private giveaway and giving the link to everyone who finds the original, but I cannot promise the key within a week or two. So this is how I'm doing it, and you're all going to have to just trust me on this.

If it proves to be very difficult, you may work together. But whoever posts a comment/IMs me on Steam with the original/the remix I know, they will be promised the game of their choice.

Thank you in advance.
