The remix of Invention15 BWV786 by J.S. Bach is frontpaged! Thank you, Newgrounds! Thank you, everyone!
But in the case of this song, I think a lot of the credit should go to J.S. Bach. He is a great musician.
Incidentally, my favorite example of Bach's song being remixed is Rumpel's Party Palace by Mike Simpson in Shrek Forever After. I don't know why, but I personally think that remixes of Bach's song tend to sound like Halloween songs.
