Adam is extremely theatrical. While he does have a good voice, he depends on theatrics and often screams to songs. While the judges often comment on other people screaming, he seems to float on by with it. I prefer his voice on softer songs like the rendition of "Mad World" which is strikingly similar to this version by Gary Jules. (Nope, Adam's not the creative genius they've made him to be.) Adam screamed the Sam Cook song tonight -- and got mad praises by the judges. Go figure.
Then there's Kris. While I don't see me running out and buying his stuff, I think he's definitely got a Jason Mraz/John Mayer vibe going on. That's very popular these days. Plus, he's an actual musician and I think he'll be writing songs as his career progresses. I've been one partial to singer-songwriters since my childhood. He did an excellent job singing "Ain't No Sunshine" once again.
In ten years I can see Adam doing reprisals of Dr. Frank N. Furter in The Rocky Horror Picture Show. In ten years, I can see Kris having a career which parallels folks like James Taylor, Elton John, and Billy Joel. Who's the winner?
BTW - Kara's song did absolutely nothing for me ... sung by either contestant.
