Evidently you don’t know what a ballard
is. Marty Robbins was the king.
Evidently you don't know the difference between a "ballard" and a power ballad by rock/pop bands. Without Googling, I know exactly what a ballad is. It has a slow tempo with often poetic or romantic lyrics. Sinatra, Martin, Como, Bennett, and even rocker Elvis made their careers on ballads.
I'm a drummer. I know what tempos are included in what types of music from blues to raggae to thrash metal to a Strauss waltz. This thread is about "power ballads". Maybe I should explain tempo?
