There is probably nothing "special" about Alistair but he does have a good voice and makes much better pop music than the crap we have to listen to on American radio. Would much rather listen to him than stupid Britney.
Only having hearing one song, my first thought was "Hm. He sort of reminds me of 'Third Eye Blind'". Or maybe a mix of them and The Jonas Brothers (heehee)... Not to say that's a bad thing. I actually quite enjoyed his music, although not enough to Bookmark it... Sorry Mr. Alistair Griffin! :(
