Has art jumped the shark after WWI?

For what it's worth, I work out to Britney Spears and Christina Aguilera and Beyonce.

I'm not saying they're my favorites by a long shot, but they sure do the trick when I'm running.

So if they're motivating, does that make them not art? Or are they not fully developed? Or are they developed in the way that they were meant to be, which apparently has more to do with movement and dance clubs?

This made me think of a now rather old fashioned, but I think is still a good way to evaluate art of any kind. You ask the following questions:

1) What was the artist trying to achieve or communicate?

2) Did they succeed?

3) How important is what they were trying to achieve, and was it worth doing?

In the case of Britney Spears she succeeded. The object may not have been earth shattering profound, but it was worth doing.
