You know the worst thing about the end of Idol (or the vote off's) - is waiting for the albums to come out for your faves. But I do like that iTunes offers all the songs this year - and polished studio versions to boot!
I just downloaded the latest by Cook (but they only had "I Don't Want to Miss a Thing" in audio - the other two were videos).
And for those non-Jason fans - you should at least preview the studio versions of his songs. Without the nerve-wracking audience (remember he's totally inexperienced), you may find you like him more than you thought you did.
