They may have grabbed attention initially as the girl version of Super Junior, but nine-member girl group Girls' Generation succeeded in winning the hearts of K-pop fans with their own unique appeals. The group made their debut in August with the single Into The World, which stormed to the #1 spot on the M.net chart within two months of its release. In response to the high demand for their first self-titled album, Girls' Generation which saw release in November of 2007, the girls are back with a repackaged version entitled Baby Baby containing all of the songs that featured in the original album plus 3 extra tracks.

The titular track Girls' Generation (Track 1) is a remake of Lee Seung Chul's 1989 hit of the same name. Rearranged by accomplished composer Kenzie, the song appeals to both young and older generations, offering tunes reminiscent of the 1980s and full of youthful energy and funk. Other noteworthy tracks include the lively, rhythmic Ooh La-La! (Track 2) composed by Lee Jae Myung, house dance number Kissing You (Track 5), and Baby Baby (Track 3), a sweet confession of love written by Hwang Sung Je, whose previous works include BoA's "Atlantis Girl". Also, lyrical ballads such as Tears (Track 7) and Complete (Track 4) offer the group's nine colorful vocals in perfect transparent harmony. Adding to the original track list are Kissing You (Track 12), "Let's Go Girls' Generation - Long Version" (Track 13) and "Let's Go Girls' Generation - Short Version" (Track 14). Girls' Generation aims to be a new generation representing all generations.
