I sometimes think Nintendo uses music sampling for their songs in video games. I know they use sounds they find in the sound library and put them in their music like they did with the chanting for the Fire Temple in Ocarina of Time and it can be heard in other games too as well.
This song here sounds like it’s from Baby’s Day Out when it gets to around 0:14 and it’s only the beginning music.
Also in the Lon Lon Ranch song, part of it sounds like “Silver Bells” where we sing “City sidewalks, busy sidewalks.”
You can hear it at the part, 0:09.
Even if it’s not called a music sample, they sure seem to use the same tune, just only a little part of it for their songs.
