This kiss-off banger finds Grimes lashing out a former friend, apathy being her weapon of choice.
I don't see the light I saw in you before And now I don't, and now I don't And now I don't care anymore
Speaking on Sirius XM U with Jenny Eliscu, Grimes said the song is about a former best friend of hers and "being really disappointed in someone who you once truly admired."
Both UK newspaper The Sun and Time magazine named this as their Top Track of 2015. Time magazine said:
"It usually takes half a dozen songwriters to concoct a pop song this spine-tingling, but Claire Boucher, who once described her solo project Grimes as the girl group to her inner Phil Spector, writes and produces her music all on her own."
Grimes wrote, directed, edited, colored and art directed the double video which features this song and the more mellow "Life in the Vivid Dream."
