Just because a album has the most bangers doesn't mean it's the best album or a favorite. Some albums have more tracks than others, sometimes 1 track you don't like can fuck up the whole vibe. Necro has a lot of bangers, a ridiculous amount.
If I had to rank them I'd prob go
Pre-Fix for Death
I Need Drugs
Not a 100% sure about it but I think Death Rap and Pre-fix should be one or two. I need drugs last. If I had to be objective I'd say Pre-Fix is his best work it has it all.
It's hard for me to rank Necro albums.
