OK, OK, OK.  I will grant that being most vocal classes are best served for the classical genre.  However, that said, shall we lose any classification in non-classical music.  Perhaps Barry White and Issac Hayes shall be equal to Pharrell Williams or Sylvester.  According to my sources (my vocal coaches, and yes even the 'Net), a countertenor is a singer who can sing in the upper fourth and fifth octaves) like an alto, ever by vocal cord adduction or developed falsetto.  I would not classify say Usher as a countertenor, but damn, I don't apologize for Timberlake using many of the hautcontre techniques vocally that more classically oriented singers use.  It's interesting to note that nobody jumps on Pharrell?  Is it that theres no comment from the peanut gallery or that non-classical singers are just substandard period (ignore the fact that some "singers" have no business in the recording industry).  I those more popular names because not everybody knows who Russell Oberlin, or Alfred Deller or Terrence Barber are.  Many people haven't had the pleasure of hearing Ben Millett or knowing who he is.  Also keep in mind that many popular music singers train on classical techniques and choose to sing popular music.  Constructive criticism and updates are GREAT!!!, everybody is human, especially me, but saying the whole article is misfactual because Justin's name appears in it is wrong.  All the terms are freely available at the countertenor page or elsewhere on the 'Net, as well as in the appropriate books.  There is no standard on classifying a voice, some will classify by the highest or lowest note, others by the middle.  So I can understand some of the controversy on popular singers.  But Trey Lorenze hit a soprano-esque note in Mariah's remake of "I'll Be There".  If you want to shift back over to more classical examples, fine by me, but also showcasing more popular examples may paint  broader and more inclusive picture of the beauty of the countertenor voice.
