Katy Perry 'Roar' Snippet Heard in Fourth Trailer for New Song 2013: 'Prism' Single Seems to Highlight Inner Strength Following Break Up [VIDEOS]

Katy Perry has released yet another teaser for her upcoming new song 2013 "Roar." This time, the "Fireworks" singer gave fans a slightly longer snippet of the song to listen to, in anticipation of the tracks Aug. 12 (Monday) release.

The fourth "Roar" teaser opens with Perry putting on the satin tiger jacket, seen in her single's recently unveiled cover. The songstress then gives two slightly angry, very intense looks at the camera as she walks through a house and to a microphone. She continues her love/hate/intense relationship and eye contact with the invisible viewer as she takes a breath.

Then, a slightly longer preview of "Roar" erupts. "'Cause I am a champion, and you're gonna hear me roar," Perry belts out, in what is presumably the single's chorus. The string of "Ohs," first heard in the "From a Meow to a Roar" teaser earlier this week, follows the blast of words.

From the short preview in today's trailer (Aug. 9), it seems as though "Roar" is less dark and angry like Perry has teased and more encouraging and empowering. Though the sampled lyrics do seem to indicate some former struggle, "Roar" seems to be more about finding yourself and power again after a tough time, as opposed to being bitingly angry. "Roar" seems to fall in line with "The Teenage Dream: The Complete Confection" track "Part of Me."

Today's trailer "Satin Cape" is the fourth teaser for "Roar." Perry has been posting short videos to her Twitter and VEVO accounts for the entire week leading up to the singles release. It all began on Aug. 2, where she set fire to her baby blue "California Gurls" wig, followed by a funeral for her candy cane corset and a kitten finding its voice.

Perry has also released teaser artwork for "Prism" and the "Roar" single cover.

"Roar" will finally be released on Monday, Aug. 12. "Prism" drops on Oct. 22.
