You're the number one regret on my list
 Number one bad taste on my lips
 Of all my favorite things I wish I hadn't done
 Baby, you're number one
 Ain't got nothing new I can sing about
 Don't even matter who'd end up walking out
 Things I can and do, things I can and say
 There's your name right at the top of the page
 You make me wanna pull you up on my stage
 Put a gold medal 'round your neck and say
 You're the number one regret on my list
 Number one bad taste on my lips
 Number one reason my heart broke
 But I might be somehow worse than her
 But I guess I'll never know
 And baby you're the best
 At making me a mess
 Of all my favorite things I wish I hadn't done
 Baby, you're number one
 Oh, oh, oh-oh, oh-ohh
 Oh, oh, oh-oh, oh-ohh
 I ain't even sure who's the second place
 If you got that far it don't matter anyway
 Had to break a heart, had to leave a scar
 Every sad song, baby, you're the star
 You're the number one regret on my list
 Number one bad taste on my lips
 Number one reason my heart broke
 But I might be somehow worse than her
 But I guess I'll never know
 And baby, you're the best (baby, you're the best)
 At making me a mess (at making me a mess)
 Of all my favorite things I wish I hadn't done
 Baby, you're number one
 Oh, oh, oh-oh, oh-ohh
 Oh, oh, oh-oh, oh-ohh
 There's a lot of broken hearts
 At the bottom of the charts
 One by one they're dropping off
 Ooh, while you'd stay right on top
 You're the number one regret on my list
 Number one bad taste on my lips
 Number one reason my heart broke
 But I might be somehow worse than her
 But I guess I'll never know
 And baby, you're the best (baby, you're the best)
 At making me a mess (at making me a mess)
 Of all my favorite things I wish I hadn't done
 Baby, you're number one
 Oh, oh, oh-oh, oh-ohh
 Oh, number one
 Oh, oh, oh-oh, oh-ohh
 Of all my favorite things I wish I hadn't done
 Oh, oh, oh-oh, oh-ohh
 Oh, oh, oh-oh, oh-ohh
 Baby, you're number one
 Oh, oh, oh-oh, oh-ohh
 Oh, number one
 Oh, oh, oh-oh, oh-ohh
 Of all my favorite things I wish I hadn't done
 Baby, you're number… one
