What is the name of the song from 50 First Dates?

I don't really remember how the song goes because I couldn't really understand it, but it sounded reggae I think? I believe it was a girl singing/rapping/reggae-ing. It was the part I think was when Adam Sandler was crying in the diner because he "couldn't read"... I think.. I remember that the song played in the diner... do you know??
