C.h.a.o.s.m.y.t.h. is from ONE OK ROCK’s new album Zankyo Reference. The guitar intro sounds suspiciously familiar. The song starts out all ballady, but the chorus has more energy. Good song.
About the pronunciation of the band name, ONE OK ROCK is an Engrish stylized version of “one o’clock”, which was the time the band used to practice.
