You are probably already familiar with the famed “feud” between Sun Kil Moon frontman Mark Kozelek and the rock band War On Drugs, which started when Mark Kozelek became frustrated with the sound from the War on Drugs’ set bleeding onto his own stage at the Ottawa Folk Fest. The conflict only escalated with Internet exchanges, a couple of unflattering songs by Mark Kozelek, and fuel for the fire provided by the abundance of music websites and blogs commenting on this issue. Some people do not find any kind of humor in Kozelek’s attack and see him as an immature jerk, while others believe that this is simply another case of the media sensationalizing things out of context for the sake of a story. Whatever side you may take, there’s no denying that this beef was unexpected and the relationship between the two parties does not have the rich history that is more typical of these kinds of conflicts. So, we’ll take a look at 10 diss tracks with more personal back-stories than the songs we got from Mark Kozelek. We could easily put in 10 solid hip-hop songs on the list, but instead, we will try to go for some variety and see how wide-spread this phenomenon truly is.
