There's alot of truth in what you say. I'm an older guy and generally do not like the new stuff thats out today. There are always exceptions and those are a nice surprise to me.
I don't know what would be considered "older", but I'd say I am no spring chicken and I do like quite a bit of new music. There's absolutely no denying there is a LOT of crap out there though. While a lot of what tends to be popular; aka pop, these days is more fad than anything of significance. That's not new, but it does seem more prevalent lately. Catchy is fine, but that kind of stuff can just as easily be a jingle on a commercial.
However, having listened to her 1st album twice, I would say that with the exception of the 3 or 4 hit songs which she has out, the rest is filler material. Because the rest is just filler, I would not recommend her to a music enthusiast. Its also blantanly obvious that shes ripping off Madonna.
A Madonna clone isn't even it; I'd actually say she is manufactured. She's the missing member of the Spice Girls or Backstreet Boys. They know they can put anyone up there with some catch crap, have some odd antics to achieve media coverage and you can make some money. That's the goal of a machine like this, not to make good music IMHO.
