If this topic bothers you, I mean really bother you... get a mirror. Seriously. The simple fact that some people get angry over this is telling. Okay, you got angry, now ask yourself why.
This site is full of folks who are wrong on a regular basis so if they think originals suck, why not let them? If they think covers are for old folks who gave up, cool... now what? IMO most of these opinions are born of ignorance or just an attempt to tweak people who apparently don't mind being tweaked.
Like you?
I play mainly covers. I don't have to do carbon copy arrangements. At this point in my career it pays better. Much better. There is nothing anyone can say about that that will upset me, particular if I know they're trying to upset me. That would make me stupid too... wouldn't it?
So if an adverse opinion about your choices really gets your knickers in a bunch, ask yourself why what mainly anonymous folks on the interweb think about something they know very little about... you, matters? If you find that it really is important count yourself in the minority of human beings and let me know how that ulcer works out.
The containment idea is a good one IMO, it'll be interesting if they all come here to share their wisdom. Or entertaining at the least.
