They were actually kind of alike in their early albums. Kanye was a lot more emotional, talking about issues, his worries things that people relate too, sometimes inspiring. New Kanye isn't the same as that anymore, he talks about how great he is, angry etc. It's funny the things he used to criticise, he's doing himself now. So not really surprised Kanye if he was influenced by Bowie especially early on in his career.
They are nowhere near the same level musically, even if Kayne's early stuff was pretty good.
I don't really care what he does, he's got freedom to do it. I mean if no one buys it then it won't matter anyway, it'll be the people that will decide whether it'll be a success or not. No need to stop him from making it, I don't think we can prevent someone doing something like that, it's wrong.
And I'm in the camp where I don't really care what Kayne does these days, don't care about it. I like to pretend he stopped making music ages ago, I only like/relate to what he used to be and the music he used to make. In some ways similar to Bowie who wasn't as good after the 70s were up though a few good songs here and there after that. But at least I felt like I respected the person still despite that.
