My brother is playing a loud zombie game. I don't like those kind of games so I turn to Louchan2's channel on youtube, and choose the playlist with almost every Touhou song from 6 ~ 12, side games included.
The reason it isn't all is because of the Youtube playlist limit. 200 max, I think.
Anyways, this is happening now. 11 hours of Touhou songs with headphones. :3
Edit: Headphones seems to make the songs more detailed than just listening without headphones. First time using headphones.
