1 Disturbed songs on new Rock Band 4 & Guitar Hero Live on Sat 08 Aug 2015, 01:08
Both songs are on the disc so maybe more songs will appear as DLCs, only time will tell.
Plus with Prayer being one there is a chance that there will be a multi-track for people to mess with n make instrumentals n other stuff
