2) He describes her as his sweet moonbeam that he dreams of. Watching her is the only drug he needs and she's the only one he's dreaming of.
3) The chorus declares his soul sister is like Mister Mister on the radio. The way she moves isn't fair and he doesn't want to miss a single thing she does tonight.
