I wonder what the thought process is behind that. Because I would think that with a sequel, you would want to do something thematically and sonically similar to the original. Work with the same people, explore similar themes, try to dissect what made the original album what it was. I don't think artists do that. They just make songs that might sound like their older work and call it a sequel just off that.
Like with Eminem when he released The Marshall Mathers LP 2. He said he called it that because people were reminded of his earlier work when they heard songs from it, but where were these songs on the album? It has nothing to do with the original, outside of "Bad Guy" and Eminem dyeing his hair blonde again. He worked on the album for over a year and at the time, he said it was the hardest he had ever worked on an album before. It makes me wonder what songs didn't make the album but could have, and maybe justified the album being a sequel.
Also, is it me, or are sequels just a hip hop thing? I don't see artists in other genres doing them. Seems like a lot of them would rather pretend most of their earlier albums don't exist and focus on what they're doing now. I know there are a lot of people that want Lady Gaga to make ARTPOP 2, but I don’t think she's actually going to sit there, call up DJ White Shadow and say, "Yeah, we need to spin the block again for this one."
