Hi everyone. This one is nowhere to be found. Some songs are on Nicovideo, but they are of inferior quality. The full tracklist can be found here. (http://taikotime.blogspot.ru/2013/09/taiko-no-tatsujin-wii-u-bashon-song-list.html)
As far as I know, some songs from this version were published as a gift CD (http://vgmdb.net/album/42707) but to my knowledge it isn't ripped. There's also a CD (http://vgmdb.net/album/45048) with 3 songs from this game by Kawagen and Takuya Nishiyama which I already have a rip of.
If anyone is willing to rip (or record) the music from the game, I would greatly appreciate it.
Thanks in advance!
