Keshia ChanteOttawa’s 15-year-old may be urban music’s answer to Avril. Like Lavigne, Chante suffers from a typical preoccupation: boys. “Why you trippin’? Why you gotta be buggin’ out on me?” she asks one on “Unpredictable.” Chante has misgivings about a second guy in “Bad Boy.” And in the syncopated “Does He Love Me,” featuring guest rapper Foxy Brown, Chante expresses doubt about yet another lad she met at “the mall in the parking lot.” As long as boys will be boys, it seems, they’ll also make good subjects for songs.
