Whitney Houston is included in those that will be inducted into the 2020 Rock and Roll Hall of Fame class. Of course, Whitney started out with her Mom "Cissy" Houston singing gospel music. And as much as Whitney was a pop star, she was also the artist of one of the bestselling gospel albums of all time. The soundtrack for the “Preacher’s Wife” is the all-time bestselling gospel soundtrack from a movie. Why is Whitney Houston now in the Rock and Roll Hall of Fame? Simply because she was one of the most singular, undeniable and successful musical talents of the last 50 years. She sold countless millions of records, influenced whole generations of singers, and still resounds today with one of the greatest voices ever heard in popular music.
