This isn't rocket surgery

I can tell by the diamonds in your eyes
It's not about the music
Read a score to decide which band you sign
When your own two ears should choose it
You must have superhuman eyes
If you can see what truly lies
Behind a page of black and white
It's only rock and roll dont analyze
By the way, it's a shame it's come to this
Machines are judge and jury
Yeah, it's swell science can predict your hits
But this isn't rocket surgery
How dare you judge a work of art
By breaking down all of its parts
When all that matters is the heart?
Rock and roll should never be this hard
