I've been doing this one on and off for a while. What I like about music is how varied and immediate it's effect is. It takes a lot of the pressure off trying to set a mood.
Right now we're got a Spotify station titled The Piano Bar playing. It's a smooth jazz type of feel so the mood is pretty mellow. Earlier in the weekend we listened to some Usher radio. He's the best. You can imagine how different the two moods were.
I wouldn't play music like this all the time. Most days we listen to the news or country or Taylor Swift. But when you need some help, there's nothing wrong with getting some help from your musical friends.
