When you got A good thing - Lady Antebellun.

Everybody keeps telling me I'm such a lucky man. Lookin at you standin there I know I am. Barefooted beauty with eyes that blue, the sunshine sure looks good on you, I swear. Oh I can't believe I finally found you baby. Happy ever after, after all this time. Oh there's gonna be some ups and downs, but with you to wrap my arms around, I'm fine. So baby, hold on tight, don't let go. Hold onto the love we're making. Cause baby when the ground starts shakin you gotta know when you've got a good thing. You know you keep on bringin out the best of me, and I need you now even more than the air the breathe.

You can make me laugh when I wanna cry...This will last forever I just know, I know.  We got a good thing, baby, woah so hold on tight. Baby, don't let go hold onto the love we're making. Cause baby when the ground starts shakin you gotta know, oh you gotta know. Oh you gotta know, you gotta know when you got a good thing.  We got a good thing baby ♪
