Lol XD this should be fun... Let's see...
Richard is known to always wear headphones wherever he goes, however, the music he listens to is never revealed by him. Some speculate that he makes his own music, some believe he wears it just to act like he can't hear anyone, but there are also those who think he is listening to naughty stuff. But whichever it is, we might never know...
Naomi is a rock enthusiast. She wears band shirts wherever she goes and has a full collection of her favorite band. She goes to every concert (that is close to her hometown) and likes every new single coming out! One thing is for sure and that is that she doesn't leave her tastes to herself. In fact, she hates earphones since that keeps her from talking to people. This is why she only listens to music at home on loudspeaker.
Lucas has played guitar his entire life and has gotten to the point where he thinks that any other instrument is "filth" and will gladly elaborate on his opinion to naysayers. However, there are only a few musicians that this perfectionist considers 'worth his time', otherwise, he only plays for himself based on his mood.
Steve is a hip hop dancer since he was a child, but he doesn't only listen to hip hop. He likes to dance so anything that will get him to move is perfect in his mind. His favorites are definitely lock-in type songs though.
I believe those are all the characters who have music related to their character... But this definitely gives me more initiative to come up with some more details for the others ^^ Thank you for this awesome thread!
Edit: LOL i forgot to share the story XDXDXD
