This is a variation on a theme (thanks @spirulence), to encourage more listening. I'll start by posting a song. Next person to post can't have listened to that song before. Comment on the song briefly and then leave a new song for the next person. This will get messy because I'm sure we'll some overlapping, so make sure you name the song you listened to in your comments. Ex.
I listened to Leslie Odom Jr's Tiny Desk Concert. I love Leslie Odom Jr and Tiny Desk but I hadn't heard this yet and I haven't heard his new album yet. I absolutely adore his voice and his versatility. He is classy AF. I'll be getting the album after this.
And I leave Hugh Laurie's St. James Infirmary Blues. I don't always love heavily orchestrated and theatrical blues, but I make an exception for this one. https://www.youtube.com/watch?v=AzEBH6DZJVk
