Wei Song composed Leave Me Alone, while Si Song did Cloudy Sky (music video above). Both tracks varied vastly in style—the former features a mid-tempo beat with the singer’s vocals lending a rebellious yet emotional touch to the song, while the latter is a slow, melancholic ballad that incorporates the lyrics of an old Hokkien folk song—and yet were included in Sun’s award-winning debut album, Yan Zi. 

“Different voices will inspire different styles of music composition. Sun’s voice reminded me of [Canadian-American singer-songwriter] Alanis Morissette’s, and there wasn’t a voice like that in the Mandopop industry then,” says Si Song.

Besides Sun, both brothers have also written songs for the who’s who of the music industry in Asia and till today, they still remain widely sought after for their compositions. But their music careers have also taken off on different focal points. Si Song manages Wise Entertainment, which consists of artiste management, music production and publishing arms, while Wei Song is the managing director of Lee Wei Song School of Music. The twins are, however, co-founders of both entities too. 

I feel very fortunate having a twin brother. It’s impossible to do everything without him. You simply don’t have the time and energy” — Li Wei Song

Growing up and working with each other has also resulted in an undeniable rapport and chemistry between the two. “We’ve been building on that since we were kids!” Wei Song enthuses. “We’ve learned to help each other with our music and complement each other’s style.”

To the veteran music producers, the route to stardom isn’t always guaranteed and they will never promise fame even to the most promising of musicians they meet. In the case of Sun, apart from her talent for singing, many elements such as a remarkable marketing team had to come into play for her career to take off.

On top of that, the completion of a successful album takes a whole team to accomplish. Both brothers emphasise that each role—from the producer to the lyricist—is equally important, even if they work behind the scenes. Si Song sums it up: “Our success is only possible because of the team and talents that we get to work with. We’re eternally grateful to them and there’s no other way to describe it.”
