Higurashi no Naku Koro ni Sui Theme Song Collection
My brother noticed this on one of those JP media upload blogs about a week ago, so I might as well upload it. I kinda forgot to do so then, but it's here now. Anyhow, this particular soundtrack features 8 songs, with most of them being variations of pre-existing ones, and it was also released on March 4th, 2015. That said, you'll find the link below. Enjoy!
