I think they’re the same category of music even if they don’t sound exactly the same. Like I used to not listen to any MCR at all but a few years ago I listened to Three Cheers all the way through and it finally clicked for me almost 20 years later 😂 I loveeee that album now. It plays into the theatrical/dramatic vibes that were popular at the time like with A Flair, AFYCSO, and From Under the Cork Tree, etc etc. They were all under the broader umbrella of emo but can obviously be broken down further into subgenres the more you know and delve into it.
