Most overrated bands?

I was raised on classic rock and like most all of it of course so many songs have been overplayed that I do to just turn the station even if I kind of like the song but I just heard it too much. On a post back on the first page or second page someone was talking about the Godfathers of heavy metal. In my opinion it's hands-down the very first Black Sabbath album Black Sabbath Black Sabbath. WhenThe Mamas & the Papas were California Dreamin - Black Sabbath came with the heaviest hitting album of the time.
I like to keep with the music from the time of my car because I'm that age too. I've turned country to listen to something different that I haven't heard on the radio a million times. And now a big of David Allen Cole and Waylon Jennings and the such. Now I know what some of my religious co-workers in the pass were saying when they said rock and roll ain't bad it's the country music that's really bad as far as influencing people.
They looked like tombstones in our yard
And I never seen him when he wasn't tired and mean
He sold used parts to make ends meet
Covered with grease from his head to his feet
Cussing' the sweat and the texas heat
And skeeterz
And the neighbors said we lived like hicks
But they brung their cars for pa to fix anyhow
