You know why they call it "pop" music? If you said because it's "popular," you're mostly right. I tend to think it's also because the music goes, "pop." As in here one day and gone the next.
The only difference between a one-hit wonder and a majority of the crap (and most of it is crap) filling top 40 music these days is that one-hit wonders disappear and those with more stick around a little bit longer.
For example, how many of these hit songs from 2007 are you still listening to?
- Beyonce's "Irreplaceable"
- Nelly Furtado's "Say it Right"
- T-Pain's "Buy U a Drank"
- Mims' "This is Why I'm Hot"
- Akon's "I Wanna Love You"
My guess is none and not because you thought they sucked in the first place. If you used to listen to those all the time, chances are that you've moved on to the next radio hit and left the others in the past. Hell, Beyonce's "Single Ladies" is probably over and done with by now if not for the fact that it's repetitive and annoying as hell.
Just something to think about...
