Alot of her popularity and Amy's for that matter seems to be other generations and critics pining for 'better' music and finding it with them. Put her back in the days when Pop vocalists like Barbra streisand, Liza and sarah vaughn sold racks of records, and I don't think she holds down the Billboard charts for 54 weeks like she has so far.

She's treated as an anomaly rather than the rule. Still, artists like her and Norah Jones show there is still consensus at times.
