@ TGJ IS A WASTEOFLIFE:

I highly doubt you're a vocal coach. If Rihanna really does have a vocal range of 3.4, then it means that range means absolutely nothing when it comes to singing ability. Freddie Mercury was a 3.5 (or something near that), by technical standards that would mean he was only a slightly better singer than Rihanna. Yet anyone who isn't tone deaf knows he could sing her under the table on his worst day.

And calling me dumb is a sure sign of your "maturity".
