I enjoy a lot of recording of beethoven, however only one of them is optimal until i discover another recording to replace it
In any case, the idea that multiple ways of performing a piece of music is a product of notated music prior to the invention of recording
A composer can only write a score. How it is played is out of their hands and the interpretation of the score is subjective enough that it can inspire different interpretation. A score may say play softly but how softly is soft (aka what decibel is soft?) etc. it was simply impossible to have a definitive performance as even if someone made a great performance, the moment is transient as the performance can't be captured and preserved and replayed
The invention of sound recording and subsequently electronic music. Means that when you write a piece of music you can mould it to create the exact performance, timbre as the composer wanted it. The idea of a definitive performance/recording can exist as you can specify more precisely how a piece should be played.
In the past what the piece of music is the notes on the score and what it sounds like varies between performance. Today the piece of music incorporate the sound of the instruments, the performance of the performer where it is indivisible to the piece of music.
For example The Beatles written Sgt Peppers, if the Flaming Lips did a cover album of Sgt. pepper, it will always be considered a non-legitimate album compared to the definitive performance by The Beatles itself. I'm just applying that kind of value towards classical music where there is a definitive performance (although he standard isn't via authenticity of being performed by the person who wrote the piece but via personalised preference)
Now you may say that is the standard of rock music and not the standard and tradition of classical music but as you see I judge all music by the same standard and make no exceptions to the traditions of any particular genre of music
