it's all good brother (except nickel back, I really despise them with a passion, they seem to oppitimise all i hate in simple face value lyrics, which dont go any where, and the "bonjovi" element, it's hard to describe, but some where down the line it sounds very insinsire (sp), that's all just my oppinion, so no body get upset please)... i dont understand why you've not chosen "bad to the bone" (I know it's obvious, but it's great, and easy to play, and your hardly seeking to expands these poeple's vast intellect, or are you?).
About Cobain, it doesn't matter what YOU think, it's what your audience does, and if it means a better response for your live show then so be it... and really that goes for the glossy nickle back stuff.
