Theres only regular "records".
And even if there were "4th gen records" Aespa or whoever wouldn't be breaking records, they would be setting records. You cant break a record that didn't exist before. That's like saying SEO Taiji and The Boyz broke a 1st gen record with their debut album selling however many copies.
It's ok to talk about your faves music for a change instead of their stats 24/7. Don't forget that. Cause 10/20 years from now nobody is gonna care how much money your faves made cause that money will be long gone. All that will matter is if their music is still good enough to listen to at that point in time.
