*Also, see this forum for Yelawolf's recently released EP with Ed Sheeran, The Slumdon Bridge EP: http://forum.trshady.com/viewtopic.php?f=5&t=143278
Additionally, I want to create a thread soon with Yelawolf's discography much like the one we have for Eminem, all help for this would be appreciated.
