Adele is incapable of singing her basic, tenor ranged repertoire (her range is mediocre and underwhelming for a mezzo soprano) and you're trying to put her in the same realm as Beyonce?

the whale billows out after C# and it's a simple middle note in the 5th octave. Pathetic and she's thought of some world class vocalist.

She wouldn't even be able to sing Beyonce's simple ballads that peak at Eb5/E5 (Pretty Hurts) or even simpler tunes like Die With You, which requires chest-head transitions that'll make Adele yodel for glory!
Enough with you people believing that vocal superiority has anything other to do with vocal ablity. You're judging the ability and skill delivered from the vocalist and yet you're talking about how beautiful YOU think they sound, despite the next soul believing the instrument of the vocalist is total trash! That's why this is subjective and isn't anchored by anything factually based. Uncanny how this simple logic seems to escape or elude most of you.
A pianist buying the most expensive, coveted grand piano, doesn't suddenly make him qualified to be a world class virtuoso.
Most of these girls here have nice, nonpolarizing, "pleasant" tones and emit emotion (something a mourning child can easily do) and that's where it ends. These qualities, however great, doesn't say anything for their vocal ability ..or lack there of!
