Music/ songwriters who should never have tried to be singers

I was burned out on Led Zeppelin like that for almost 20 years.

I finally got over it about 10 years ago, and have been going a little deeper than the traditional radio songs.
(Except for Misty Mountain Hop, who doesn't love a Hobbit themed hard rock song?)
I never get tired of Zeppelin, especially the album tracks that don't get airplay these days.
