At this writing, Zack's smash hit has a staggering 71 million views on YouTube. Moreover, a new song was commissioned to be used for What We Could Be with the same title as that of the series.

Filipino singer Zach Tabudlo has put his own English language spin on the song's original Thai lyrics about unrequited love.

Whether he’s serving smooth RnB with the chart-topping single “Pano” or groovin’ to touches of soul and funk with “Akin Ka,” Zack Tabudlo demands attention with his words and his music.
