Dunno why, maybe I kept listening to 夕陽無限好 and 阿牛, these two songs kept ringing in my mind. For the first song, it's the beat that attracts me, it's sort of 中慢版, making it comfortable to listen. And for the second song, it's the content that attracts me. I am still "chewing" its lyrics. I remembered one of his songs talking similar things, 喜帖.

Pop songs... try to sing it without the lyrics, you will find the melody is so simple.
