As much as I would have liked to see Mig win Rockstar:INXS, and as much as I thought Marty would have been a better choice in some ways, I can see why INXS chose JD. I don't think he should have been able to claim it as an original song during the competition, but whatever, I wasn't the boss, and he was able to present to INXS the one, compelling, inalienable reason why they should choose him.
That reason is Pretty Vegas. It is half written by INXS, so it sounds like their music, but it is a thousand times more exciting than that revolting bit of drivel called Easy they had JD sing as their first song as a whole band (a whole new band? perhaps). I also like it more than Us, which JD butchered during the series because he couldn't be bothered learning it before he went into the studio -- like the Pretty Vegas gamble, that paid off for him.
Being as Pretty Vegas is a joint effort, written for the magic of television (yeah, I know, I am piushing it to call realtiy TV magic), it would have become legally problematic had INXS not chosen JD as their new lead singer. There is a certain element of voicework, too -- I think his voice is better suited than Marty's to INXS's work (though I am not sure I could say the same thing with regarrd to Mig's voice); and JD is more likely than either of them to draw one of the bigger groups of music consumers -- teenage girls. JD also seemed more likely to be willing to bend to the will of INXS than the other two. In the end, though, Pretty Vegas was a deal clinhcer.
And why not? Pretty Vegas is a cool song. It bounces along apace, but has enough of a darker side to it to differentiate it from the "happy rock" that mainstream radio stations here seem so enamoured of. The well rehearsed INXS riff contrasts quite appealingly with JD's fresh vcoice and lyrics. And the megaphone and the attitude just add that little extra something to thwe whole thing. If I was already a millionaire, I'd sell my future for a song like Pretty Vegas too.
