I understand what you both are saying, but there are radical instances where an artist has changed in a way that left them so completely out of my general taste in music that there was no way I could keep liking them.
One example would be Gwen Stefani. I really love No Doubt, but I liked their albums less and less as new ones came along until Gwen went solo and I absolutely despise that album. I know that situation is a little different because it is a band and then just Gwen, but I went from being a big Gwen fan to being like, uhhhh, you ever going to make good music again?
Anyways, my point about Vanessa's post is that she sounds like she's ready to make a considerable jump as a songwriter, which is always a good thing. I wasn't really talking about her sound. I'm still not sure exactly what direction she's leaning in when it comes to that.
