Some observations from the trenches.
It does not matter whether you are talking Protestant or Catholic, both have their problems, and they ALL stem from Religion, rather than following God, via the Scriptures, the Prophets, and his Holy Spirit.
Both the MegaChurch and the Lapsed Catholics are a “mile wide and and inch deep”. If they want to know God, they need to go to God rather than than rely on somebody in vestments or a cool pair of sneakers.
As to “Hymns” vs “Contemporary” music. When the Hymns were written, the WERE Contemporary. We should judge rightly, not just lumping into groups.
And many more were written than are currently used ... that which was dreck when, for example, "Amazing Grace" was written has vanished into deserved oblivion.
Sturgeon's law ("90% of everything is crud") applies even to sacred music.
And that is where you are so wrong.
“As to “Hymns” vs “Contemporary” music. When the Hymns were written, the WERE Contemporary.”
There was a time when secular music and religious music were separate, but since they happened at the same time they were contemporary, BUT DIFFERENT. The musical praise offered to God should always be distinguishable from what secular music offers.
There are some modern songwriters who do, however, get things right like Keith & Kirsten Getty, and Stuart Townend who, while they are popular with the youth, also write the sort of music which works equally well with an organ in a more “traditional” setting. There lyrics also contain good theology.
