In March 2013 a new greatest hits compilation called ICON: The Best of was released in the USA .  Included on this album was Sun which Belinda had been performing live since 2012, including during the live recording of Live from Metropolis Studios.  The song, originally written by singer-songwriter Gabe Lopez was then sent to fellow Go-Go’s singer Jane Wiedlin who tweaked the lyrics.  Lopez, Carlisle, and Wiedlin are listed as songwriters. The song was released in the UK on 20 May 2013 by Demon Music Group and received regular airplay on BBC Radio 2, hitting the Top 40.
