freakin' weekend, baby, so she's picking up her ladies—presumably in her jeep—and hitting the local party spot". The fourth track "Age Ain't Nothing but a Number" is the title track for the album and it is about "a young girl pining for the love of an older man, and her telling society that it doesn’t matter the age difference between the two of them". The song contains an interpolation from the song "What You Won't Do for Love" performed by Bobby Caldwell with the lines "I got a thing for you, and I won’t let go.” The fifth track "Down with the Clique" is a hip hop-inspired song and on the song, Aaliyah displays a "silky cooing" with her vocals. The sixth track "At Your Best (You Are Love)" is a cover of the song originally recorded by The Isley Brothers. The song was described as a "sweet", "vintage soul ballad" and it gave Aaliyah a chance to "ditch the tough-girl posturing" according to Billboard. The seventh track "No One Knows How to Love Me Quite Like You Do" has been described as a "sensually" up-tempo "crush" record and, lyrically, it is about Aaliyah being satisfied and how she is "made to feel like a goddess". When discussing the record, Aaliyah said "Every girl looks for that one person who is going to love them right. That song is saying, when it comes down to it, I like how you satisfy me." The song features a guest rap appearance from Tia Hawkins, who brings a "comic relief" with her raps, telling the listeners R. Kelly is "spitting tracks as if it were tobacco." The eighth track "I'm So into You" features another guest rap from Tia Hawkins. The ninth track "Street Thing" has been described as a "pretty standard slow jam" and it is about having devotion for another person. During the bridge of the song, Aaliyah sings about climbing the "highest mountain," and swimming the "deepest sea" to prove her devotion. The tenth track "Young Nation" is about Aaliyah "aligning herself with an entire movement". The eleventh track "Old School" is about merging an old school style with a new school style, the opening begins with "Here's the old school / With the new school". The final track "I'm Down" has been described as a mid-tempo rap-soul ballad and it is about "one person giving themselves fully to another".
