It's been months since I've had the album, so I don't remember where I picked it up. Honestly, I think I found it when I was randomly searching folders with anything Higurashi-related, and that album just happened to show up ><; sorry!
That's fine with me! I also received your request for the Sinfonia album, unfortunately I do not have the original RAR of it anymore ><; but, I can re-strip the tracks from each video and compile it all into one album, if you'd like. Quality should not be affected, I don't think. If you don't mind waiting till Monday (going on vacation this weekend), I can get it to you then?
