I'd love to do something experimental like rap one day. I'm a big fan of names like Del the Funky Homosapien, Lupe Fiasco, Mike Shinoda of Fort Minor, (Not Linkin Park, shut up) and De La Soul.
Rap/Hip-hop has soul, (At least, some of it does) but I feel like they're words I'm not worthy of making any attempt to relate to out of sheer natural ignorance. If I did do anything, I'd do it Beastie Boys style so it doesn't feel like I'm intruding on sacred ground - I couldn't even do traditional hip-hop graffiti without feeling like a jerk.
