While the tracks may be catchy on their own, the album as a whole runs the risk of being forgettable, and even boring, with its similarly sounding numbers. Nonetheless, many of the songs have melodies that are easy on the ear; that said, Train Of The Four Seasons (四季列車) and Gong Gong With A Headache (公公偏頭痛) can be considered noise more than music, leaving you itching to skip to the next number.
Smile (傻笑) features a collaboration with Chou's apprentice, Cindy Yen Yong-lin, freshening up the number. Much of Opus 12 is rather superficial, but this track - in addition to Love You No Matter What (愛你沒差) and You Are Everywhere (哪裡都是你) - stands out in that Chou's emotion is able to come through in his lyrics. All in all, the album has its moments, but it's hardly Chou's crowning achievement.
