"We could do an album or we could do it viral/Spread it like an STD you got back in high school," boasts Sean Foreman. Give the Colorado "crunkcore" duo accuracy points: Streets of Gold is about as pleasant as a case of genital herpes. The formula is the same: dopey electro rock bolstering "raps" about drinking ("Wake up next to pharaohs hung over in Cairo") and getting girls to "touch on" their privates. A Dr. Luke beat and a screwball Ke$ha cameo make "My First Kiss" listenable, but otherwise this is grim stuff — a soundtrack for beer-pong tournaments.

“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.
