OOh nice (after clicking the video and reading description) I didn't knew you were into music making. This is MIDI, right? If you want to I could put the file in the download section (if it's a different file format I could convert it to mp3). I like it, true to the original but with some beat.
Unfortunately, I haven't finished listening to it yet and due to the nature of low volume videos I won't take any chance and will listen it at low volume anyway
EDIT: Finally, it was not a screamer, so I am relistening at max volume now
EDIT 2: It appears to be keyboard, nice job ^^
