Google Trend slopes separate trends from fads?

Google just launched their new Google Trends along with a bunch of other stuff. Trends lets you see how popular themes are and gives you a historical graph showing volume of searches on a specific topic.

As a test I looked up Arctic Monkeys (one of Magnus' favorite bands)and then Van Hunt (one of mine) to see what the differences are.

The search histories are quite interesting. The Arctic Monkeys slope is a sharp rise followed by a sharp fall, symbolic of a fad, whereas the Van Hunt slope is steadier, perhaps showing something with a more lasting impact.

Of course I don't think this tells you anything else about my music taste versus Magnus' and definitely doesn't speak to any differences in our character or anything deeper like that.
