Expert+, Expert, and Hard with Full Lighting Effects. This is a mashup song by Ghost in the Machine on Youtube. These two songs mesh together so well I think they make for a better beat saber song than each individually! There’s a few parts where multiple vocals are happening at the same time. Each of the different difficulties follows a different set of vocals. I would love to put together a video demonstrating this, but you’ll just have to play each for now and see what I mean. Enjoy!
