Tom

Bon iver. The man loves the sound of this band and recommends it to anyone if he has the chance.

Loki

Imagine dragons. The music is good and the lyrics even better. His favorite of the songs is demons. Not only because he relates but it's a very good song in general.

James

Rock and roll. I don't even need to specify it's literally all the same but he loves it.

Thomas

Seeing as to how no one was listening to the Neighborhood in 1900, I believe his favorite music was classical.
