Their fourth album "We Rule the Night" is a very soft album compared to all their prior releases as it includes their sound of metalcore, but also incorporates new ones to their style such as pop rock and nu metal. There is also a fair use of acoustic guitars as well as mainstream-influenced synthesizers. Clean vocals are also featured as the lead vocals compared to their previous albums were both harsh and clean vocals were leading together; on "We Rule the Night", however, the harsh vocals have been mixed behind layers of distorted guitars, acoustic guitars and mainstream synthesizers, and the clean vocals were left untouched to appeal to a younger, more mainstream audience.
