Tell Me If It's Chilly Outside

I’ve got several friends with their own personal taste when it comes to music. Tapping into that vast well of musical selection is what I’m planning on doing.
 
Every week I’ll listen to a different band/artist. I’m going to give someone 4 weeks and they will hopefully help me in expanding my musical knowledge.
 
I already know who the best person to help me start this endeavor is.
