Hilburn is right.
He does need a new name for the kind of music he gets excited about. Because for the most part, it's not real rock 'n' roll. What is rock 'n' roll?
Rhythm. The beat. The riff. The hook. Improvisation. Simple melodies and harmonies. A loud, hot, sweaty, somewhat aggressive, somewhat rebellious type of music.
Rock 'n' roll has never been about "meaningful" lyrics! What was so meaningful about the lyrics of "Hound Dog"? "I Want to Hold Your Hand"? "California Girls"?
