Even according to the young, youth is wasted on the young. There may be no group as jaded or as nostalgic for the innocence of childhood as teenagers, who are both eager to prove they're real adults and starting to realize that a lot of parts of adulthood suck. Ahmad's "Back in the Day" is the gospel for this group, the words of an 19-year-old sharing the wisdom of old age and wishing his only responsibility was still finishing his homework. The blueprint for many songs by nostalgic teenagers since, "Back in the Day" perfectly captures the wistful vibe of the rearview look with its warm chorus and deeply descriptive verses. As a result, ever since back in the day, the song's been a classic.
