Kansas City rapper Mac Lethal is no stranger to viral fame. His “27 Styles of Rapping” video racked up more than 11 million hits on YouTube, and it seems that his latest venture is about to land him in the public eye once again.

Local satirical rockers Something and the Whatevers gave a darker rendition about the universe in “The Good News,” the first track off their recent release Epic Fail. This is often accompanied with a video about the Universe at their live shows.
