These "boring old hymns" leave the modern worship and praise songs FAR behind in their spirituality and truth content!
The "modern" hymn writers are quite often spiritually immature babes in Christ that their efforts in (trying to) writing Christian music pieces are woefully inadequate!
Thankfully I listen to both modern and old because they're equally amazing in composition. For example, this is a song from the modern rock band Soul Junk
Father, You alone are holy
Full of majesty and grace
Purify your church
So we can worship You in spirit
So we can worship You in truth
Jesus, You alone are worthy
You have made us one with God
Come renew our hearts
So we can feel Your resurrection power transforming all our lives
So we can sing & dance & lift Your praise
Free of idols
Free of blame
Free of sin
Free of shame
Free to lift your Your holy name Lord
I agree though, the hymns of the past are amazing! We should not neglect their beauty and truth! However let's not forget that the same God who moved in the believers of the past still moves in men to this day, inspiring them to create works of beautiful art his name
