It took you five years to answer THAT? ^^ It's definitely still a shame that they are not in this quiz. And don't tell me they are from Long Island please ;).
MGMT seems an odd choice. They formed and recorded their first music while at Wesleyan (Middletown, CT) and aren't really associated with the NYC music scene. Perhaps you are confusing them with Vampire Weekend? They have a similar origin story but started at Columbia (NYC).
Also... no J Lo?
New York had INFINITELY more influence on his music than Minnesota ever had.
great quiz still ;)
