You don't think Madonna is talented? Wow! I guess taste is very individual, but I think you are just howlingly wrong. If you don't think Madonna's lyrics are poignant, I suggest you aren't listening.

As to complexity equalling talent, who else doesn't make the talent cut for you? Bob Seger, Bob Dylan? The Beatles? Folk singers in general?

I think your definition of talent is snobbish nonsense.

Madonna produced great art, and in way way to reduces to "booty shaking."

You are dead wrong.
