Would you consider Chris Cornell a “showoff”, vocally?

The other day I showed my friend Slaves and Bulldozers, and he said it was pretty good, but he said he felt like the chorus (specifically the “What’s in it for me” part) was a little over the top. He said it felt less like genuine vocal expression and more of just like “look what I can do with my voice”. Either way, I don’t have a problem, because there are plenty of flashy musicians who are awesome, but didn’t know what y’all thought about it.
