"Dayman," the song from It's Always Sunny In Philadelphia that you're absolutely not going to be able to get out of your head for the rest of the day now, has received a very long-overdue metal makeover! Brian Nichols and crew did a great job with the cover and really made it his/their own, all while sticking to the original.
