Nightwish: Tarja vs. Anette thing..?

These people need to get a life. Band line ups change all the time. I personally preferred Tarja to Annete, but I still listen to Nightwish. A change in singer is not always successful such as Motley Crue with John Corabi, Iron Maiden with Blaze Bailey and also successful such as Sammy Hagar in Van Halen and Brian Johnson in AC/DC.
