Cody Simpson (born January 11, 1997) is an Australian pop/R&B singer-songwriter from Gold Coast, Queensland. He began to record songs in his bedroom during the summer of 2009 and put them on YouTube, where Shawn Campbell, a Grammy-nominated record producer who has produced for Jay-Z and other artists, discovered him. After signing to the US record label Atlantic, Cody released his debut single, "iYiYi" (which features American rapper Flo Rida) on May 15, 2010. The teen performed this song at the 2010 Australian Kids' Choice Awards as the closing act, where he won the Fresh Aussie Musos Award.
This is the second single from Cody's debut EP, 4 U. He wrote the song with R&B/Soul singer-songwriter Lil' Eddie and American pop and R&B singer-songwriter Krys Ivory. Cody told J-14 about the tune: "'All Day' is a little bit more mature than 'iYiYi' is. It's a fun, feel-good song just explaining your feelings for a girl in a fly way."
David Ovenshire directed the song's video, which was shot in January 2011. It features cameo appearances by Jessica Jarrell, Aaron Fresh, Jacque Rae, and Madison Pettis.
Who writes a song about a name they found in a phone book? That's just one of the everyday things these guys find to sing about. Anything in their field of vision or general scope of knowledge is fair game. If you cross paths with them, so are you.
