If Amy Winehouse cornered the bad-girl retro '60s market in 2006, Duffy showed there was room enough for a good-girl competitor in 2008. On the back of her heady breakthrough single, "Mercy," Duffy delivered 2008's best album. Rockferry was a gorgeous, soulful debut, with many of the songs focusing on the desire to leave or move on from a toxic relationship. A smash success in Britain, Rockferry also caught on in the US, where "Mercy" was a minor hit and Rockferry went on to win the Grammy Award for Best Pop Album.
Best: Mercy, Warwick Avenue, Stepping Stone, Serious, Hanging on Too Long
