For his song "Do It", Vanness Wu required the skills of an excellent rapper. It came as surprise when he revealed that Vic Chou would be responsible for the rapping.
Vic is known for his inability to enunciate, making him seem like an unlikely candidate to rap. However, Vanness discovered that Vic could actually rap very well back when they were singing karaoke during their F4 days. At the time, Vanness even said to Vic, "Someday when I release my solo album, I'll look for you to do the rapping,". That someday has indeed come.
