Koi ga suteki na Kisetsu is one of my favorite H!P songs of all time. These setlists are like an amazing timewarp. I was thinking the other day that the great thing about CM essentially being shelved in 2007, was that their discog then didn't have the opportunity to become so bloated ^^;; (not to knock MM's or anything, but damn that's a lot of music to never be performed ever again). Now the concert setlists will contain only songs from around H!P's first peak era, and it's a great way to re-captivate older fans who kind of peaced out for Platinum-lead H!P, while also showing newer material/gems from within the Platinum era we may have missed.
tl;dr - basically revived CMCG makes me simultaneously nostalgic, and excited for new material to come.
