Jason Mraz. Always be one of my favourite singer ever since I'm in the high school. I think his unique touch of the song not just he is good in writing a song but also difficulty for others to sing the melody/swing note like him. It goes with Taylor Swift too. BTW, did you notice that Jason Mraz getting hotter over the time? Just like Adam Levine and Zac Efron. Well, i'm just saying~
