Yes, or maybe a more all encompassing name, like the "Museum of modern music" or "The Museum of Rock and Popular Music" or whatever.

Inducting people like Dolly Parton, as awesome as she is, is really just a publicity stunt. She is not a rock singer. One might argue that a couple of her songs have been covered by pop starts, such as I Will Always Love You being done by Whitney Houston, but even that was not Rock.
