Let me just use classical music as an example. But it applies to all art styles.
Early early classical...if you can call it classical.. from the 17-18th centuries was pretty much trash.
All of the music was composed using a few different modes with highly specified rules. There was no creativity. It sounded dead.
Then you get to Buxtehude, Bach, and Pachabel. They were all madmen. All of them sucked at school. Bach didn't even have a good attendance record. They were creative artists and played from the heart.
Eventually the genre they created died because it became too theoretical, too mant copycats sprang up. You can find plenty of people today who make music just like they did, the same quality too. But it's not from the heart.
Live from your heart or you'll just die, slowly.
