Can someone give me the lyrics to 'la razon', please?

It's the Spanish version of 'The Reason' by Hoobastank -- I can find youtube videos with the ACTUAL song, but I'm unable to find just the plain old lyrics. I do not want the literal translation, I want the lyrics to the song, in Spanish. Since I don't know the artist of 'la razon', and I know it's not Hoobastank singing the Spanish version, if anyone knows that would be great, too. Please and thanks. And it's not the one by Juanes.
