For me it’s very easy: A-ha’s “Take On Me”. The video was absolutely amazing. Youtube it if you’ve never seen it.

Beyond that song, and a couple of others that were at least listenable, their songs really, REALLY sucked.

When I hear the term, "one hit wonder,' my mind takes an automatic ride to Men Without Hats' Safety Dance.

Their follow-up album was actually quite good, but never got any traction...

This has been covered by a country /soft rock band and is also very good,

Beyond that song, and a couple of others that were at least listenable, their songs really, REALLY sucked.

However, the follow-up single "The Sun Always Shines on TV" also did quite respectably. It was a #1 song in the UK and a top-20 hit in the US. So however much it sucked (personally I didn't think it was that bad, but that's just me), A-Ha really don't qualify as OHWs.
