What do Styx and REO Speedwagon have in common besides the obvious cheese factor, being aging rock musicians, and sharing the stage at Dodge Theatre this weekend? The '70s and '80s power rockers have seven tracks featured on the Rock Band Music Store catalog for the wildly popular video game. Three of Styx's biggest singles — "Blue Collar Man (Long Nights)," "Renegade," and "Too Much Time on My Hands" — were recently re-recorded for Rock Band. REO Speedwagon fans can rock along to jams such as "Ridin' the Storm Out," "Roll With the Changes," and "Take it on the Run." Can't Stop Rockin', the new collaboration between Styx and REO Speedwagon, recorded in anticipation of the Can't Stop Rockin' Tour, will be available this week for Rock Band.
