Somehow I have a hard time imagining that their singing is any less painful than hearing the agonizing screams of tortured souls from the bottom of the deepest pits of hell. Maybe I'm exaggerating, but the people who gave them money probably only did so to make them shut up.
Yeah, you're probably right, it's just to make those annoying noise go away. If you've been in a developing country and see those beggars singing on the side of the road, you'd understand the feeling, it's probably similar to yukkuri singing.
Am I the only one who have this unnatural urge to stomp the hell out of the Reimu, btw? Even without sound I still think their singing is annoying, and I'm usually tolerant to scums!
Dunno about you but each time i had seen beggars that either sing or play instruments they were in general good artists with shit luck, since their music was fantastic unlike yukkuri singing, specially with scum lyrics like this.
Also don't be tolerant to scums, they are the enemy, mokomoko! the only ones acceptable are niceheads and neutrals (and this ones are debatable) but the scums and shitheads are the enemy that must be purged, for the world's easiness!
