In all honesty, many of my favs are simply favs because they've made a very distinct impression on me, I can't fairly say otherwise. In many cases I've simply listened to certain recordings so often and having been so impacted, I often find other rendition make me feel alienated from a piece of music that I love, a slight difference in color or phrasing and I get so moody; I ask myself, 'Why did I even bother buying this?'
I know this forums is mostly involved in talk on new releases. and it is not as though I'm adverse to new things, but I bet many can relate, either pocket book wise, or the fact that, like me, it is tedious work getting reacquainted with yet another interpretation, not that I'd rather be digging ditches.
