You are using objective language for subjective criteria when you say Christian pop is "poor music". There are many aspects of a song that can be judged - which do you mean?
The vocal performance?
The musical performance?
The recording / mix ?
The songwriting?
The theology ? (in Christian music alone)
The production?
The "vibe" ?
When most people say any type of pop music (including Christian) sucks, they usually mean that it lacks the latter. Not edgy enough. Too sugary-sweet. In high school, it's considered vapid because cheerleaders like it. In adulthood, because "soccer moms" like it. These are social judgements, and should have little bearing on whether or not a song is judged "good".
Like it or not, Phil Collins is, by all objective means, and excellent song craftsman. He knows how to "craft" a good hook.
I wouldn't be so quick to dismiss an entire genre of music as poor. After all, "I can only Imagine" came out of Christian Pop, and will most likely still be sung in Churches a century from now.
Alot of what is produced in pop music today is music crafted "by committee" and sung by whoever has the most star power. This music is not usually the best quality. As the article stated, there is alot of Christian radio music produced by committee, also.
There are exceptions, but overall the playlist could be improved greatly. Don't you agree? And I'm not talking about more stuff just because it's "edgy" -- that doesn't have anything to do with well crafted music.
