As if all new dinobots, autobots and decepticons are not enough, Transformers 4 trailer has released its latest soundtrack featuring Imagine Dragons new track “Battle Cry.”

According to director and producer Michael Bay, the new track will be used in the “critical points in the film.”

"We're incredibly lucky that Dan, Wayne, Ben and Daniel were available to work with us," Bay has said of working with Dan Reynolds and Co. "I remember being drawn to the emotion of 'Demons' and 'Radioactive' the first time I heard those songs, and I knew I wanted that same energy and heart for this movie. They've created a really epic, otherworldly sound for 'Battle Cry'."

Meanwhile, executive producer and director Michael Bay revealed that "Age of Extinction" will pave way to a new trilogy. On that note, Bay thinks that this fourth installment to the franchise should not be tagged as "Transformers 4," since this is a reboot and not a continuation of the previous trilogy.

"It's kind of like a new Transformers," Bay explained. "We had three, the first trilogy, and this is going to be the next one." The next...trilogy? "Yeah, it's the first of a new trilogy," he admitted after shortly hesitating. "I'm not necessarily sure that I'm doing [the others], but that's what it's meant for."
