Just the intro, got it by ear.

Song: Moshimo Taiyou Ga Nakunatta Toshitara
Artist: One OK Rock

     C                 G
Moshimo taiyou ga nakunatta to shitara
     Am                     F
Dare hitori to shite ikite ikenai
     C                   G
Machijuu wa sawagidashi aseridasu
     Am                   F
Kono saki nani ga okoru ka wakaranai
