AJ has debuted and girls are going wild, but I'm still unimpressed. Sure this guy can dance, but can he sing? Legendary R&B singer Kim Tae Woo from g.o.d. came to help out AJ with some singing lessons. Check it out here (thanks to jaeuraznMV): After hearing AJ sing, Kim Tae Woo gives him some advice and shows him how it's done:

The tone of your voice is very good. It's a trendy tone that will do well. Something that is most important in a song is rhythm. It's something that can make this song good or bad. Be sure to put emphasis on rhythm...etc.

Kim Tae Woo shows that humor of his towards the end of the video - He reassures AJ that he will do well and decides to go off. Right as he was about to leave, AJ asks him if they could take a picture together. Tae Woo immediately starts patting his head, even though he has a hat on, and then starts complaining about how he has to take a picture with someone as good looking as AJ. Tae Woo also teaches AJ how to form his name with his hands and tells him, "Remember, it was hyung(Tae Woo) who made it." Although AJ's singing part wasn't that hard, Kim Tae Woo was right to say that his tone was trendy and will do well. AJ is very lucky to have such a great singer such as Kim Tae Woo helping him along his career. With this kind of help, AJ, who's just turned 19 year old, is destined to succeed, no?
