If you think about it, it's kind of obvious that many (but not all, of course) Nessa fans would listen to Avril and Michelle. I mean, when they all arrived on the scene, about the same time, the alternative to Britney etc. was:
a)Vanessa Carlton
b)Michelle Branch &
c)Avril Lavigne
...pretty much. I love some of Michelle's songs, and I like some of Avril's songs, without considering myself a "fan" of either, like I do with Nessa. So... I'm not really sure what my point is here, but maybe someone will get it, lol.
