You've hit on a really interesting point with construction kit songs. It is now common knowledge that anyone can download the tools, read some magazines and *produce* a track. What's a shame is that there is still very little knowledge of how to *write* a track.
There are plenty of blogs, forums, articles out there, countless books on theory (I'm sure I could find something second-hand for pennies....) So why are there entire subgenres of music that are unable to execute a basic modulation? And why do the handful of pop songs that modulate up towards the end do it so, so badly? Has there ever been a hip-hop track with a tempo change? Why does every emo band think that "vocal harmony" means doubling the line up a third? (Not intended as a slight on the specific genre; at least they acknowledge the presence of more than one musician in the band to do the singing).
We need to get people listening to better-written music. The industry filter was never a big help.
