Guy Sebastian seems to be making a dent in the US market lately. His latest single, Who's That Girl, is now available on iTunes in the US. You can find it here. It is a great song, and he is joined on the effort by Eve, who is quite good in the song and the video. The two also co-wrote the song for the singers Twenty-Ten album. It has been catching on with some of the radio stations here, so if you have a favorite station in your area, you might want to request it!
While there, I see you can also purchase the video and single for Never Hold You Down on iTunes as well. The song is off the Like It Like That album. It was written by Sebastian and David Ryan Harris.
