Before Dream5, there was avex audition 2006. This audition led to the discovery of multiple talented individuals, such as Shigemoto Kotori (Off-topic: Arai Hitomi was another). Kotori became a regular on the NHK program, Tensai TV Kun MAX. In November 2009, Tensai TV Kun MAX held auditions for four boys and girls who could sing and dance. This led to the discovery of Hibi Mikoto, Takano Akira (the only boy in the group), and Oohara Yuuno. Tamagawa Momona didn't actually take part in the audition, but was added by the judges at some point.

PVs:
It's hard to find the PVs online, so forgive the quality. This is mirrored and missing the end, but Tabidachi no Uta is a great ballad.

This song is more fast-paced, but has no PV.
