The girls of Fruitcake aren't prodigies in the style of international teenage stars Christina Aguilera or Jessica Simpson. They are average-sounding singers, with voices not yet fully developed. The voices of Fruitcake blend pleasantly, but there isn't much depth, and various performances sound thin and tinny.
A variety of musical styles are explored on Fruitcake. Several songs feature a dance beat, including "Di Na Kami Beybe" (We're Not Baby Anymore), "Tumayo, Sumayaw" (Stand Up, Dance), "Thank You Mr. DJ," and "Crush Kitang Talaga" (I Really Have a Crush on You). "Whoops Kirri" is centered on a ska-styled rhythm, while "Daddy Cool" is funky, and the ballad "Puppy Love" is a remake of Paul Anka's famous tune.
The quality of songwriting on Fruitcake is quite high, better than most Philippine albums. Also, the music is more adventurous than usually heard in the country. The girls' thin voices, however, temper any excitement generated by the album. The shrillness heard on "Daddy Cool," for example, irritates a listener's nerves. Still, considering the group's adventurous choice of material, it will be interesting to see how Fruitcake develops.
