Lyric discussion by WiseOldGuy 

Cover art for Countdown lyrics by Lindsey Buckingham

He is going to get married with the girl he loves. He is out of lost and found state of getting confused and no one claimed ownership.

Positive vibes song and when madness fades, loving feeling lingers and he's certain things are turning around

@WiseOldGuy good call, man. Never thought it could be about marriage, but makes perfect sense, if you analize the song. It's about strong feelings, after all.
