Escape Club is not a one-hit wonder.
Who's fault is it that a song that was a decent hit in its day gets little if any airplay these days, or airplay only on certain shows or formats? Definitely not the artist's. Having a definition of "one-hit wonder" status that depend on "everybody" remembering the song is a crime against art.
Rupert Holmes doesn't think of himself as a one-hit wonder. If you never heard of him until you read his
bio on his website, you wouldn't think of him as one; he barely mentioned his "one hit."
