I've got you under my skinI've got you deep in the heart of meSo deep in my heart that you're really a part of meI've got you under my skin

I've got you under my skinI've got you, deep in the heart of meSo deep in my heart that you're really a part of meI've got you under my skin

The song continues with the singer struggling against, yet ultimately accepting, a deep infatuation, featuring lyrics about trying not to give in, sacrificing anything to be near the loved one, and ignoring a "warning voice" to surrender to the feeling.
