"Undisclosed Desires" is influenced by contemporary R&B such as Timbaland , using a drum machine and vocoder-laden vocals. Matt Bellamy plays neither guitar nor piano on "Undisclosed Desires", whilst Chris Wolstenholme plays slap bass. According to Matt, the song is very personal in nature, relating to his relationship with his girlfriend.
It's the 3rd song on the album The Resistance
I know you've suffered
But I don't want you to hide
It's cold and loveless
I won't let you be denied
