How is the Mutual Core app. The 2nd best song on the album.
You don't really do much. You have to connect these two terrains together and when you touch the tiles, they produce sounds. It's hard for me to explain because I'm too lazy to tell you in depth while I'm on my iPod.
I thought Tune-Yards and Fleet Foxes were a lock for my top 2 albums of the year, but this is right up there with them.
Thunderbolt is slaying me right now, the breakdown in Crystalline is otherworldly, Cosmogony is downright beautiful, and as everyone else has already said, Mutual Core goes down as one of her best recordings.
The 2nd best song on the album. 
I want to so badly though!
