Well said Frogman. I agree with your thoughts. A deliberate blending of sounds occurs naturally in live performances, and is likely to be purposely engineered into many recordings.
I don't think there is any particular virtue in complete isolation of different instrumental lines unless the mix is so dense as to nearly obscure a particular instrument almost completely, making the listener strain to hear it.
