Artists choose to write shockingly upsetting music for a number of reasons: To express extreme emotions or to provoke a visceral response in listeners or say something about a particular issue or for the shock itself. Sometimes, they're presented as true story warnings, as in Bushwick Bill's "Ever So Clear." And sometimes they're the fulfillment of a fictional persona, as in DMX's "Bring Your Whole Crew." When done right, they can be artful, but sometimes a disturbing song is just a hollow gross-out. Either way, shockingly violent imagery has been a part of music forever -- we've just really honed the language in the last 30 years or so.
Obviously our extensive list of most disturbing songs is, well, yeah, very disturbing. So there's your warning. For those who don't want to read this list, we don't blame you. Mom, I'm sorry for this.
