Help!

Im looking for a song by a female artist with a really high pitched voice and one of the words in the song is "smile" i cant think of it and its killing any help would be great!

Ok, wild guess time...

In the catagory of new songs, try "Bubbly" by Colbie Caillat

In the catagory of "high note" singer, try "Fear", "Hold On" or "I Love You" by Sarah McLachlan
