If INXS wants to play venues bigger than county fairs, they would be wise to pick JD. Without doubt he is the best possible choice of all the contestants.
First up, no way no how that a woman would be picked. That may anger some, but this is not an equal-opportunity profession, it is entertainment. INXS songs are written from a sultry male perspective and the music is arranged accordingly. A female voice can perform them adequately, but a high-pitched female vocal is so far removed from the music INXS has created, it just doesn't work.
Second, Mig is a freakin joke. He is proof that at least one of the Village People experimented with heterosexuality. His vocals are weak, yet not as weak as Marty. He lacks projection in his upper and lower register. His style is so effeminate I see it turning off both male and female fans of INXS. Pretty boy rockers had their chance in the 80's. It was a miserable failure. Australian viewer/voters are so intent on an Australian replacment it has clouded their objectiveness.
Marty is an interesting singer who has the illusion of intensity, but it only comes from the place inside of him that wants to win the show and become famous. It lacks a genuine quality. It doesn't come from a life of passionate experiences, nor is it the reflection of a person with an intense charisma. Couple that with his weak vocal control and you have two strikes against him. His attitude that he will "escort" INXS into the new millennium seals his fate for first-place loser. He is a fraud.
JD clearly is the best choice for a multitude of reasons. Like it or not, he has a raw sexuality that appeals to a large percentage of women, and indirectly, men. People can nit-pick about his nose or mouth, but Freddy Mercury had similar "flaws". If anything JD's semi non-conformist image is very appropriate for INXS. JD's vocal tone has a crispness and clarity that is unmatched by any of the others. He has a masterful control of his vocal tool. He doesn't pop his "p"s, he doesn't draw breath into the mic. His musical skills beyond singing are superior as well. His writing and arranging abilities are HUGE advantages that have a signature aspect to them. You can hear JD's voice and know without doubt that it is JD. Something that cant be said for the others. That is an extremely critical component for any musical performer. I am stunned by suggestions that Mig is "easier to get along with" than JD, therefore INXS should choose him. Great logic if your looking for a soul mate, not so good if your looking for a person with the proper vocal and performance talent needed to sell CD's. Some feel JD has an attitude problem. What I have seen is defensive reaction from the contestants who are intimidated by him, and redirect their fears as being "his bad attitude". A perfect example was Susie saying JD's criticism - of her criticizing him on the show - hurt HER feelings.
Finally, the non-verbals of the band very strongly point to JD as their personal favorite. The one-on-one interview with the band very much revealed them to be mentally rehearsing arguments as to why JD should be the singer, as opposed to their post-interview discussions with the other three which revolved around what each of them lacked.
If I was a betting man with $100, I would put $90 on JD, and keep the other ten for myself.
