I'm glad that I'm not alone in that opinion. Unfortunately those guilty of such have standard stock "get out of jail free" phrases. "I play it like I feel it" is mostly untrue, the performances on the whole are NOT spontaneous but carefully/or not so carefully worked out beforehand. The problem is that I can see right through them and can instinctively know if it's genuinely "Not knowing' or if it's just, as is oft the case, not bothering. There is NO excuse for wrong chords or melody, when we all have the internet and a less than one second search will yield answers to almost everything, with the exception as to "why make excuses when the lack of diligence and caring is patently obvious."
I completely agree with the if we're playing for fun, anything goes, (BUT not in public, the listener MUST be respected.) it's by mistakes and accidents under those private conditions that we improve (Those of us who can recall all are lucky, but memory is also a matter of training, just like musicianship, musical prowess and dexterity)
Have you ever wondered how a concert pianist can play a complete concerto with no sheet music. One of the first things he learns is memory, pattern recognition and mathematics.
All good musicians have those capabilities..If you don't nurture those assets chances are you'll never get beyond a certain point with your music.
Probability theory is a good subject to study If you wish to be able to instantly recognise chord types and progressions.
