I'm pretty sure a lot of those pop hoes forgot how to have o good era. The last era that was really good was Katy perry's era Teenage dream. Right single choices, a lot of music videos, good promo, great sales and colorful. But how should an era exactly be to be perfect?
Discuss.
Commercially: 21 was obviously perfect, Title, 18 Months & Motion are great. Rebel Heart was going to be awesome if it weren't leaked.
Artistically I'd say Electra Heart was a pretty flawless era, Ceremonials was a very good one too. Plenty of visuals to accompany the songs is always good.
