like it or not, some MCs are not about battling,,, i might be wrong but Zubz isn't out there claiming he's a battle MC. he's a songwriter,,, and a respected one at that.
having said that, i don't think people need to get so touchy about this subject. battling is part of the culture of hip hop. it's natural to want to hear your favourite MCs flex their skills. verbal sparring is entertainment. when it's live it shows you are quick-witted, creative and calm under pressure.
it's not just about dissing. i've seen MCs lose battles because they come over too hardcore, lacking wit and imagination, even if they were the most aggressive.
Zubz doesn't need anyone to step in to protect his honour. I doubt he will take part because he doesn't need to,,, and because it's just not his thing. fair enough.
Maybe we should suggest the two of them collaborate instead of battle? ;)
