The 'Cheap thrills' hit maker is in for another surprise yet sensitive video this time when she launched her latest music video- 'The Greatest' with a heart rendering performance of 49 dancers in all (same no. of people who died in Orlando shooting).

Released on Labor Day, the song also features an inspiring verse by Kendrick Lamar.

While the video stars Sia's favourite dancer, Maddie Ziegler.

Based on the Orlando incident of shooting when a man in his thirties shot down close to 50 people while brutally killing all the party-goers of Pulse Club. It sent shockwaves all over Orlando for many lost their loved ones consequently.

The heartwarming video dedicated to the deceased, shows  a message "#WeAreYourChildren" in the beginning after which the video shows a mansion full of artists who represent dead bodies lying on floor on each other, then, Ziegler walks in dancing through the way and bringing life to the laid bodies while communicating strongly of hope and an urge to fight back together after painting rainbow colours manually on Sia's face with tearful eyes - a symbol of LGBT community, for many who lost their lives that horrific night were gay. Sia is herself bisexual.

Finally, everybody danced together merrily as the unfortunates may have done that night delivering an almost realistic experience to viewers. And as the ill fate had it, all the dancers fell flat on the floor to reveal a wall destructed all over by bullet shots.

Filled with heartfelt emotions, it waters a viewer's eyes with lyrics "I won't give up", "I got stamina" to let the pain of endurance fuel vengeance to take rule over for "the strongest survive another scar may bless you".
