Lou Reed's Berlin is a disaster, taking the listener into a distorted and degenerate demimonde of paranoia, schizophrenia, degradation, pill-induced violence and suicide. There are certain records that are so patently offensive that one wishes to take some kind of physical vengeance on the artists that perpetrate them. Reed's only excuse for this kind of performance (which isn't really performed as much as spoken and shouted over Bob Ezrin's limp production) can only be that this was his last shot at a once-promising career. Goodbye, Lou.

“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.
