Found a keygen with this song. I could listen to it for hours ;D. It's a nice relaxing song, so I thought to just make an hour mix and share it, I bet there's lots of keygen song fans out there :P. So yah enjoy.

EXTRA INFO:
Since so many have asked in comments, I got the pictures from a friend years ago and the last few in the end I found randomly on google.
About the music, I have no idea where I got it from but I know it was some installer for a game or a program. Recorded it and made to mp3 then edited to a loop version for this video.

As it was requested I added short and long version for download:

If it doesn't download directly, right click on the player and "save sound as"
