Training does not give you taste. I have tons of training as well. Majored in vocal music, and music business. Worked for a record label and as a concert promoter prior to having children. Fact is, some good voices have no style, and some great stylists aren't the best singers. Let's just agree to disagree.
The only ability which Taylor exhibits, is the ability to appear enthusiastic. He raises his fist and laughs with his mouth open and cheers and claps his hands. If I needed to hire someone to look enthusiastic, I would hire him. The characterisitc that has gotten him this far is his visual spirit. That is not going to be enough to sell records or gain national success in the entertainment business. His quirky dancing won't be enough either.
