7-11 songs vs. hymns

Another poll type entry.
Why do we assume that the "7-11" songs are more "spiritual" than hymns? In case you don't know what a 7-11 song is, that is a chorus where you sing 7 lines 11 times.
We have at least one maybe two whole generations who have no idea what the hymns of our faith are, what their histories are, what the depth of spiritualism of the songs are.
I am sorry but "A Mighty Fortress is Our God" is a deeper more meaningful song then many of the modern choruses sung in church today. "Blessed Assurance". "Love Lifted Me". These are just a few of the most powerful songs ever written. We are missing out. Just because it is in a book? And just because it is put up on a screen and once a month the same two or three hymns are sung (one or two verses only) doesn't teach or even introduce the hymns to new generations. Is this all in the "we have to appeal to the masses" thing?
Chime in.
