[13] David's humorous "YouTube (A Love Song)", was uploaded on December 30, 2006, and brought him "overnight" fame.

He wanted to release his songs in an album, but as he was already technically a signed songwriter/producer at that time: He had to go through legal procedures and accept a variety of contractual conditions.

[18] On July 7, 2011, Choi released his third music video, for his single "By My Side", once again a collaboration with Wong Fu Productions.
