OK - it's all been determined by many progressive think tanks - liturgeists, LifeTeen, most religious ed folk (most, definitely not all - my parish's staff is part of the exception, thank God) - that Christian rock and sacro pop is what gets teen butts into the pews.
But - check out this interview with Dr. Barbara Resch.
Side note: NONE of my kids (ages 21, 19, 13, and 9) support sacro pop at Mass. Do they like rock and roll? Sure, they do! But not at Mass. They know where the musical line is drawn.
Hat tip to Jeffrey Tucker at the NLM. Oh, Jeff - only one spot in your whole post where I beg to differ...
For adolescents who keep current with popular music trends, much contemporary Christian music has a dated sound with a greater appeal to the "fortysomething" generation.
Not this "fortysomething". At least not in church anyways. ;)
UPDATE 10 AM EST: The Curt Jester has a nice idea in light of the above -- how about Life Tridenteen? Its Mass, and its accompanying banner (gotta have one, I guess) looks kinda like this:
