Encounter, Meet
When you ride your scooter on the ground listening to music under the sun, you're bound to encounter a bunch of new people! They hear your music playing as you scoot by and they come out to meet you.
Picture all of the people you encounter as you ride your scooter, spreading your music around town.

None
Everyone you encounter wants to bare their soul (そう) to you, literally. They're all coming out to meet you, pulling back their skin and showing you the soul ghosts inside of them.
"We love your music, look at our souls!" Uh oh, this is turning into some kind of horror movie. You better scoot a bit faster or you might meet an unfortunate fate.
