How many of you have heard of “Cheap Thrills”? A lot I bet.

You probably thought that Sia was only back for the summer and she now she is done. Well, think again. Sia is coming back with even stronger and more powerful addictive hits.

Her album, “This Is Acting” is blowing up on the chart during the back to school weeks. Some of the notable hits include: "Alive" , "Unstoppable" , and "Bird Set Free."

The album has a 4.5/5 rating on Itunes. Many are saying that her songs give them strength and make them believe in themselves. While others are complimenting her on beautiful and haunting voice in amazing ballad songs.

Along with the album, her new single “The Greatest” is another hit that is making dancer, Maddie Ziegler, a star again through the music video. Some believe that the video was a tribute to the victims of the Orlando nightclub shooting because of the massive and catchy chorus connection with a powerful message of #weareyourchildren.

Just in case you haven’t seen it yet, here it is:

To me, Sia is a great singer, songwriter, and psychologist. She touches her listeners’ heart through lyrics, rhythm, and through the stories of the songs. Her songs eventually made my back-to-school days better.
