Hey, I'm sorry if I sounded kinda snotty, I'm just not in the best mood right now and I guess it's showing a bit. I understand where you're coming from but so much of this is subjective, after all...hence the original note-for-note debate! It did get me thinking that it would be an interesting study...get ahold of the original studio recordings of some truly great bands (not sure who, offhand, but we'd establish some kind of standard via listener surveys, perhaps), mute the bass tracks, overdub the bass tracks with any number of average/good bassists (again, I don't know how we'd determine this, it's just hypothetical!)...then mix it up and see if the average listener could tell the difference. I guess sometimes I forget that not everybody else knows as much about music as people like us do, or understands what it takes to make an album in a studio, etc. I have a bad habit of forgetting about the "average" consumer and assuming that they're on the same page as me, when in fact they probably aren't! (Fieldy is a case in point, ha ha!)
To get back to the original topic, it is interesting to me how certain bass lines have become so completely essential to certain songs, that playing anything BUT note-for-note would be almost blasphemous. Now there's a question...how does a song achieve that level of notoriety?
