Define Classic

Something bugs me folks. People say Michael Jackson makes classic music. I don't deny that...Why? Bcoz 10, 15, 20+ years later, his music has insane replay value. Some of these same folks will hop online & scream that Drake has NO classics. Drake makes fast-food music. Mind u tho, his music that are 10-15yrs old are getting mad replay so I don't comprehend their logic. Perhaps someone who's a real music connoisseur can explain what is deemed classic 🤔
