Pink is quite a good artist. I think she is incredibly consistent with songs that are unique and of good quality. She really just does different things than conventional pop stars and that is commendable. She sets a good example for younger fans. She's just so different that she's hard to describe.
I only kinda peripherally got into Pink by accident, just from general pop culture inundation and repetitiveness of songs being played, oh and that Britney Spears/Beyonce/Pink Pepsi commercial, but she is pretty good, I think, and I didn't know anything about her being a good example or anything (that's really hard to believe so I'd have to read up to find out why people say this - she doesn't really look like someone you would say that about, but maybe that's just my bias), but I enjoy her stuff - much to the consternation/ridicule of some friends and family.
