Think of eras that
completely bombed (Breathe In. Breathe Out, Sucker, etc.) - any era that did not spawn any top 40 hits AND failed to go gold (in pure sales) in the US.
How would you re-design the era to make it a moderate success?
NO TROLLING. So, don't stay stuff like ARTPOP, PRISM, R8 ('cuz the album ain't out yet

), or any other era that does not fit the criteria above.
