Eminem just can't stop making music for the underdogs and all the kids who don't have ideal lives by any means. Sia joins him on his latest, "Guts Over Fear," another testament to where Em came from and what it took for him to get to the top. Anyone who's ever heard Slim Shady knows he came up a tough road, and even the rapper himself knows he's worn out that story in his verses, but he also knows it's a story that needs to be told, no matter how many times. For anyone who ever thought Em was writing for anyone besides his fans, "Guts Over Fear" makes it clear that Shady was simply clawing his way to the top and now has more than a few tips for anyone in a similar situation. In this case, Marshall Mathers just may be offering the best advice out there.
