This song is really frustrating to path for vocals, because there is no path that doesn't waste OD in one way or another. There aren't really many reasonable options for vocals, though, so I'm a little surprised no one else found this path. He has a little extra OD on guitar/bass here and there, (2nd guitar activation, 1st and 3rd bass activation), and he doesn't have vocals activating for those last couple points at the end, but otherwise our paths are eerily similar.
