Organ Donor by DJ Shadow to the anime Hellsing & Final Fantasy VII: Advent Children.
Actually a portion of this was being used for a DVD menu background I was making when I was moving my Hellsing and FFVII AMV's to a TV-ready DVD for my personal use. Mostly to clear some space and show people who did not have computer access. However, when I put the clip I made to this music...it was just so cool that I had to take the clip and center an entire crossover AMV around it.
