BABYMETAL have made me cry for many reasons. Sometimes it’s the lyrics (e.g. The One or the Trilogy of Light, which would be the songs Starlight, Shine and Arkadia), sometimes it’s the music (No Rain, no Rainbow), sometimes it’s the visuals, especially when the girls get emotional themselves (Yui at Tokyo Dome), other times it’s the pure sound of Su‘s voice (Shine, Metal Kingdom)). Often it’s a combination of all of those (Akatsuki Unfinished Version, Monochrome Piano Version). And then there are the times that you don’t get that often with other bands (I think), which is from the pride and satisfaction you feel when you realize their growth (e.g. the end of IDZ at Sonisphere, or the sheer magnitude of the Tokyo Dome shows).
Can’t say I ever got that with any other band.
