Remember that rumor article of the Taiko 3DS songs we posted last week? At least one of them is confirmed to be legit. Wrath of Requiem, an old classic song last seen on Taiko Wii 1, is in the game.
From my own copy of Famitsu DS+Wii July 2012:
There's the title right there in the lower corner. Although not much, it does provide a little more credibility to our rumor list; they might be completely accurate!
