If you're looking for a fun song, maybe can't stop the feeling by Justin Timberlake? That's like the fun-nest song I know, Hahaha! It definitely uplifts the atmosphere. Or Happy by Pharell Williams? Hahaha just my opinion though they aren't like love songs haha. There's another song called something Best Day of my life, I think. Haha pardon me, I'm not too well versed with wedding songs.
