I could go on for days about the greatest one-hit wonders. I could also carry on about artists who were labeled one-hit wonders but weren't. It depends on your view of what constitutes that second hit. Top 20? Top 40? Hot 100?

I think as long they had multiple Top 40 hits, they are NOT a one-hit-wonder.

Commonly mislabeled one-hit wonders include folks like Corey Hart (whose second hit was Never Surrender), A Flock of Seagulls (Space-Aged Love Song) and Fine Young Cannibals (Good Thing).
