This song really fires and cheers me up; It really becomes her, if you ask me. Mai is my hero; she sings very beautifully, and she's smarter than me when it comes to language skills (She's a multilingual woman who speaks English, Chinese, Korean, and Japanese, just in case!) Overall, I wish I could love such a cool and attractive lady like her! I would be cheerful if Mai cheered me up! Best of Hero - that's the very song for Mai and her fans as well!
One more thing I noticed about this song is Best of Hero is such a typical party tune that you may be so excited when you listen to Mai-K's Best of Hero! I would be happy to sing Best of Hero esp., if the party contains karaoke equipments!
