Mr. Right

first of all i think it's "CAN always change your mind, and you can't change mine"

i think some of the other posts have the right idea. But i from listening to the lyrics and watching the video i think the point is more that he might not be good enough for her but at least he makes her happy.

if you look at the video there are two couples. there's the couple with the curly haired girl who seems to have the wealthier boyfriend. he buys her nice clothes and buys her nice meals and nice gifts. He's got a car and he drives her around but she doesn't appreciate any of it and pays more attention to her phone than she does to him.

then you see the other couple with the girl with the dark hair with the blue streaks in it. she has a poor boyfriend. it shows them shopping at a thrift store, eating burgers on a curb, she needs to drive him around because he can't afford a car and when it's her birthday he gives her a cupcake because he can't afford to buy her anything but she is happy with him and doesn't need him to spoil her at all.

when it shows the two couples at the end the girls hug and afterwards the curly haired girl glares at her as she walks away because she's jealous of how happy the other girl is. during the whole video it makes the point to show how disappointed the curly haired girl's boyfriend is that she doesn't appreciate any of the stuff he does for her like the whole time he's thinking "what a bitch" and that she's probably just staying with him for the status of dating a guy with money even though she doesn't like him.

i know that the meaning of songs and the meaning of videos don't always match up but it is something to consider.

just paying attention to the lyrics i'd say that he's saying that he is crazy about his girlfriend. he only has eyes for her but he doesn't really know what she sees in him when there are plenty of other guys who might be better suited for her that she could be with.

i think the chorus and meaning of the song is more about how the rest of society sees their relationship than what he really thinks about it. that's why it says "maybe i'm a shot in the dark" because he's not society's ideal picture of a good boyfriend so she's taking a chance at being with him rather than going for the wealthier guy who can take care of her. she's the "morning light" because it's easy to see why he'd want to be with her. but he's saying that despite that maybe he is the right guy for her and maybe he can make her happy and that she should give him a chance because she can always change her mind but he knows that he'll always want to be with her.

it's about how some people will see a beautiful girl who seems to have the whole package and could probably get any guy she wanted but she's with some "loser" who is poor and not very good looking and they think she deserves better than that guy and wonder what she sees in him. this song is coming from the point of view of the guy she's with who nkows that that's what people are thinking when they see them together.
