Amber Tamblyn, Alexis Bledel, Blake Lively and America Ferrera shine in this film version of Ann Brashares' chick-lit best seller. Working from a deft script by Delia Ephron, director Ken Kwapis labors hard so that guys won't cringe (too much) as four teen girls, of different body types, pass along the same pair of lucky jeans during a summer of love and loss.

“The A Team”

This debut track from the then-20-year-old British singer-songwriter has a dark story behind it. Sheeran says he culls songwriting inspiration from "viewing other people's situations," which, for the heroine in "The A Team," involves drug addiction and prostitution that began as a teen. Sheeran paints the woman's trials with haunting imagery such as "But lately her face seems/Slowly sinking, wasting/Crumbling like pastries." "I did a gig at a homeless shelter, [and the song] is about one of the women there. It's her story," he said.
