Kind of obsessed with "Wonderful World" by James Morrison. I love the tone of his voice, and it's such a song where you're just driving in the car, spring day, windows down, and sing. Although it talks about wanting to cry, but that's besides the point. I love it.
First heard it from a contestant on American Idol... Alex Lambert (not Adam). Sadly, he just got voted off. Yes he was awkward and shy (performance-wise), but did you not hear his voice?!? Amaze.
