Unsurprisingly, it comes across a lot better when you actually get to hear the words (and the bass, and the lyrics). What's more surprising is how long it took the song to come together.
West first mentioned it in a GQ interview last July, saying it had the sort of lyrics "Jay would normally say". But speaking to Radio 1 last week, Sam Smith said: "You know he hasn't even finished that song?"
"I said to him [at The Brits], 'what are you guys doing after?' and he said, 'I've got to go to the studio and finish that song I just performed.' I thought that was amazing."
Perhaps the extra work went into sampling Paul McCartney whistling, which is how the song ends. According to Rolling Stone, the section appears to be a re-recording of a song McCartney wrote in 1969 that was inspired by a Pablo Picasso painting of a guitarist. I kid you not.
Here's the song in full. You can buy it on iTunes now.
