The singer is smitten with a girl he's been seeing. He thinks Lisa'a so beautiful that she's out of his league(It's like she's not even a human being), but he understands her(nobody has you down but me), so that's how he believes they work. He does such a cool thing with the lyrics when he says,"I behold the beauty, but the beauty gotta hold on me" What he's saying here is that he'd only admire her looks and have her fall in love with her, as per usual, but he's fallen in love with her, When he says "I've been singin' oooooooh" he either means he's been so lovestruck by Lisa that he;s been sighing at how beautiful she is and how lucky he is, or he means that they have sex a lot and it's part of the reason he's so infatuated with her. So, basically, he's in love with Lisa, an amazing girl, and he can't believe it.
