Lyric discussion by Poetica 

Cover art for This I Know lyrics by Juliette And The Licks

I can't believe more people haven't commented on this song! Its such a beautiful song. The lines 'it's just an illusion, this I know' really resonate with me. I think she's talking about loving someone and wanting that perfect relationship but them not feeling the same. sigh- surely everyone knows the feeling of unrequited love.
