Click to listen to Chickenfoot's 'Three and a Half Letters'

Sammy Hagar, Joe Satriani, Michael Anthony and Chad Smith have no problem finding a groove on Chickenfoot III, the confusingly titled second album by their Cabo Wabo hobby-turned-globe-trotting-alliance. They remember when hard rock meant funky stuff with misogynistic machismo on top - see brontosaurus burgers like "Alright, Alright." But the band plods more than pushes, and while the riffs stick, the songs generally don't. The unemployment report "Three and a Half Letters" and the gas-guzzling road-burner "Big Foot" get by, though: It's hard to hate big-boned butt rock from guys clearly making it because they still love the form.

“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.
