Sometimes you need music to help you work/study or even sleep. Here's my functional music trio:
Khruangbin's music is great in the background to drown out the noise and let you focus on your work. I just heard of this group a few days ago and already love them. Thanks 
Here's Khruangbin playing- Maria Tambian
Pink Martini is another great band to play while you are working or even as background music when you're having a dinner party.
Here's their song Sympathique:
My third song is one I play to help me fall asleep. I hardly ever get to hear the end of the song because I'm already snoring. It's not boring, but very relaxing. Here's Yes playing "The Revealing Science of God" off of their Topographic Oceans album - Warning - don't play this song while driving:)
