Agreed. There's also the issue of falsetto versus natural range. It's funny to see Thom Yorke right next to Freddie Mercury with similar ranges, because Thom Yorke uses falsetto all the time, whereas Freddie Mercury typically didn't. It would not surprise me if Mercury's range was far larger on the high end than Yorke's.

To be clear, that's not a criticism of Yorke--there's a lot more to vocal talent than range, and I'm actually a huge Radiohead fan.
