The essence of Gagaism: a relentlessly catchy chorus and a pummeling club beat power a song that's grand and tawdry and joyful and melancholy – a story about how love hurts so good, and so bad. Mission statement: "I'm a freak, baby." Tender come on: "I want your horror/I want your design." Singalong refrain: "Rah, rah, ah, ah, ah/Roma, roma ma/Gaga, ooh la la."
