i like Thank You but am not blown away. her vocals sound great and totally happy with that. the production is better than I Love You but not much IMO. it still sounds rather karaoke-ish to my ear.

also the song builds nicely at the very beginning but then stops. I'm not saying it needed to repeat the hysterics of One More Chance from back in the Masser days. but i feel like the song never goes anywhere.

i've only listened to it a time or two so i'll need to spend a bit more time with it. but those are my initial thoughts
