Is Rock Music dead?

Honestly, Rock has been going down hill the last few years from what it use to be, Im a big time rock/ metal head and most new stuff bands I once loved put out.. Is crap Disturbed lost connection when they started to add Dubsteap crap to it as did Korn. Most times when i'm driving I can hardly keep it on a rock station for too long cuase it's ether

1. Crap that I just can't get into/ feel or
2. WAY over playerd/ repeated on the radio (Medicate, Zombie, etc)
