I found a better suiting taiko background, so here.
The storyboard is making the taiko background misplaced, to fix it, copy this from the .osb (or here).

Then open the standard difficulty .osu and paste in there, find:
//Storyboard Layer 3 (Foreground)
Leave the taiko difficulty how it is.
Here's a wall of text for the standard difficulties.

Change the rest, not my difficulty, or delete the .osb, but that's no fun.
