Nice
The video of the guy playing it it nice, but really unnecessary.
Believe it or not, I actually listen to recomposed performances of classic (and recent) videogame themes like this almost more often than I listen to more traditional music. Classical Piano, Jazz, Soft Rock, Hard Rock, Country Western, RAP, Heavy Metal, Latin...
every genre.
I have at least a dozen or so versions of the "Kraid" theme, as part of the over 3,000 game tunes I have downloaded over the years, and the music from the Metroid games, ( mostly the original and SuperMetroid ) remain some of my favorites.
OC-Remix
OneUpStudios
VG-Mix
These are some of my favorite sources of Videogame Music. VG Mix has been down for redesign for a long time, but it used to have an even wider library of user-created remixes than OC, and You can still find some interesting WIPs in the forums. I hope they bring the archive up again soon.
