Is it normal to get annoyed when...
...when people bash musicians when they chance their style or do something out of the ordinary?
For example, Avril Lavigne changed her style from dark to more happy, and everybody was bashing her. It was fine. Same with the Black Eyed Peas. There more poppy now but still as good. And every review on Maroon 5 says that they are bad because they changed their style after Songs About Jane. Bands evolve people! And Britney Spears, she grew up after Oops I Did It Again, so of course her music will change.
Is it normal?
