Let's take KATY PERRY's single perf as an example...

Chart performance:
• HIT (#1 - top 3)
• MODERATE HIT (top 4 -10)
• FLOP (top 11 and below)

Sales:
• UNDERPERFORMANCE ( a hit with sales less than 3 million)
• FLOP (sales below 2 million)

...how about your fave's standard? Is it that high or not?

By standard do you mean average over their career, or today?

#1-#10 : Hit.
#11-#20: Moderate hit.
#21- #100: Flop.

And if the single isn't at least platinum in the US, it's a flop.

whoa, brilliant idea,

Beyoncé

Chart performance:
• HIT (top 10)
• MODERATE HIT (top 40)
• FLOP (below #80 I guess)

Sales:
• FLOP (< 1M WW)

Album sales less than 5.5 million are considered an underperformance. Her singles performance doesn't really matter at all. She gets 4 top 10s per era based on the debut weeks of her lead single and promo singles, gets like 2 hits and sells A LOT of digital tracks...and then disappears on tour leaving the rest of the singles to have success on their own for the most part. Besides a few performances, she doesn't really do much for her singles starting from the 3rd (sometimes 4th) single.

Single positions:
#1 Hit
#2 - 20 Flop
She's never charted outside the top 20 so idk the rest.

Single sales:
400k - 600k: hit
<400k: flop

Album positions:
#1 hit
#2 flop

Album sales:
300k - 1 million: hit
<300k (aka A Million Lights):

These are UK figures btw.

average over their career

Katy Perry

Hit - #1s for more than 4 weeks (eg. I Kissed A Girl)

Moderate hit - #1s for 4 weeks or less (eg. Dark Horse)

Flop - Non #1s (eg. Wide Awake)

this is too high not to commend

Taylor:
Flop: Album selling less than 5.5 million copies.

Only 3 hits so far + 6 moderate hits + 10 flops (including featured)

Only the nation's sweetheart
