Endicott, Hill and artist Santigold co-wrote "Monday Morning", a song for Christina Aguilera's album Bionic (2010). Dan Martin of the NME wrote in his album review of Bionic, "Perhaps best of all is ‘Monday Morning'. Written with Santigold and The Bravery’s Sam Endicott, it’s a Day-Glo disco jam that sounds like Gwen Stefani doing ‘Borderline’."
