Look. To me, until the last few hours, until I enraged the horde of Meatloaf lovers, Meatloaf only had the one song that I knew of. He was the guy who would do anything for love. That's what I knew him for, and nothing else. The way you are all defining 'one hit wonder,' that's what he was to me.
Apparently he also sang Paradise by the Dashboard Light, which I only know because it had some part in that godawful Josie and the Pussycats movie.
I did not know that was him when I heard it. I did not, and still don't care. Maybe he doesn't mathematically count, but when it comes to songs he's known for, I've only ever heard the one. Don't crucify me for my life.
One hit wonders are generally considered cheesy, and low-quality. This is why I count music that doesn't hold up in the same category. Because cheesy, low-quality music doesn't stick. They're different, but in spirit, they're similar.
