I have to say I never noticed any abundance of snap/crackle/pop anywhere but my cereal.
Most of what I picked up there were things like the Grateful Dead and they were pretty good.
I know that for instance, any soundboard recordings for the Dead were removed I think, so that all that remained were audience tapes. I imagine audience tapes have more snap and crapple from uncontrollable sources like the rest of the audience. I guess it depends on the source....
