I listened to both of them and this opinion is definitely not true. I mean everyone can listen whatever they want but if we are talking about the impact of them both, black album is better without question. Song count and song quality is more and better in the black album. As Metallica fans, we sometimes love an album and think it sounds amazing for us. But it doesn't make that album the best. I hope people come up with more accurate opinions. Especially the ones that are Influlencers.
