can K-stew sing?

U be the judge!
Clips from "Into the Wild," that random Sean Penn movie based on that Jon Krakauer book:

(FYI if you're curious, the 1st song is apparently co-written by K-stew for the movie, and the 2nd song is a cover of a song Bonnie Raitt has covered, originally written by John Prine, called Angel from Montgomery. K-stew can play some guitar apparently.)
I think she's OK but most people can probably sound OK after a few voice lessons. Besides, it's her job to be talented!
And what's up with her hair at 0:27???

Also, as a friend of mine says, most really talented people are REALLY talented. Like Meryl Streep? Damn gurl. She can act the hell out of anybody else and she is actually a good singer, as we heard in Mamma Mia. Ben Barnes can act AND sing too. So can Nicole Kidman and Ewan McGregor! Thus proving, really talented people are REALLY talented.

*But this begs the question--is K-stew REALLY talented?
