My cousin did something similar to his wife, he played the Imperial March from Star Wars. Something like that is funny for about five seconds, and then you're left thinking oh god why.
I'm really not familiar with Terranigma, but I think the Hometown theme, at least, would be good for a reception.
As for Zelda, that's also something we're looking at. My fiancee actually is thinking about the LttP's credits as her processional theme. If not, we'll use it during the reception.
Still a bit too churchy, also a bit too busy. Part of why I'm looking at 8-16 bit era stuff is nostalgia as well as fidelity. I really like chip music, and how it's low fidelity, and how it's more about developing a melody than a soundscape.
Nah, too cheesy. I think that might be overdoing it.
Sadly, never played Earthbound. My fiancee has, so she might really like the suggestion. I like what I'm hearing.
