If you were wondering why BUTAOTOME’s BOOTH didn’t have any digital release on sale… We have the answer.

Touhou Doujin Music Distribution/東方同人音楽流通 opened a BOOTH store, where you can find all the albums they distribute, including BUTAOTOME’s releases! BOOTH provides flac, mp3 and m4a files as you choose, which makes it a better alternative over iTunes and Google Play. No lyrics sheet/booklets are included.
