Songfacts®:

• This Alive track finds Jessie conceding her happiness in love over an atmospheric piece of Pop. "That's the last song we wrote for the album," she told Digital Spy. It got sent over by Stargate and Benny Blanco, and Claude [Kelly] and myself were like, 'Thunder, thunder, thunder'. We just started writing and had it finished in about half an hour before I went to the airport to fly home from New York."
• The song's music video finds Jessie dancing in the desert as lightning fills the sky. The former Voice coach reunited with Emil Nava for the clip - the director previously helmed her visuals for "Do It Like A Dude, "Price Tag" and "Wild."
• Fun fact: The sound of thunder travels about 1,100 feet per second.
• This song was inspired by Jessie J's religious beliefs. "Thunder is a dedication to God," she told British newspaper The Mirror. "That's why in the video I'm levitating, that feeling of being lifted to the light."
  
  Jessie added her Christian faith took on an important role in the development of her Alive LP. "I remember I prayed a lot when I worked on this album and it's not something I've ever spoken about openly," she shared. "I've very much enjoyed bringing my beliefs onto the album. I think it's important that whatever your beliefs are you use them in your day-to-day life."
