It's a toss up between KTF and TD. While TD is my #1 favorite album in every music category in music history, if splitting hairs I'm going with KTF as the absolute best album based on vocals alone. Songs like Believe, KTF, ITA, BOR, DC, Blame It On The Love Of R&R, Little Bit Of Soul, Save A Prayer, and Starting All Over Again just blows my mind...
