People do too much on her, but OOTB was a great album. It came out when I was in HS so it's connected to a lot of nostalgic memories. Same goes with Paramore's sophomore album which is in my top ten albums of all times list.
The Reminder - Feist
Ray of Light - Madonna
Lungs - Florence + the Machine
The Fame Monster - Lady Gaga
Alright, Still - Lily Allen
The Stoop - Little Jackie
Warrior - Ke$ha
