Recently we ran down our list of Roadrunner's best beards, and we figured that was a good theme to hang this week's Spotify playlist on, too. So here it is - music made by the men behind the hair. Tracks by Dream Theater, Killswitch Engage, Korn, Lynyrd Skynyrd, Machine Head, Nightwish, Slipknot, and Soulfly! Go listen!
