"We got a lot of requests saying, 'I want to hear XXX's boss battle theme!' There are many different colors and variations regarding what series and boss corresponds to the XXX. It's even hard for us to sit down and try to decide which boss battle song would be the best to play. That being the case, we've decided to arrange several of them into a medley.We hope you look forward to finding out which ones once the concert begins!"
