OK, interesting. I see "Oh, Pretty Woman", I think Roy Orbison. LOTTA chords-and a fun bass line (in our group I doubled the gee-tar riff at the beginning and at the end of each verse).
I get it. To listen to one chord things on the radidio is boring. To play a one chord thing might be sorta OK, especially if one gets a groove going with 'the percussion section'.
