No, what is unbelievable is you continue to infer other people are ignorant when your ignorance is quite clear. The irony here is other posters are using the proper context, whether popular or in the more proper historical sense, for a ballad, but you are not.

Perhaps it is because English is not your first language (and based on how you write, more likely third or fourth down the list), but a "ballad" by its very nature requires lyrics. This has been the nature of ballads since the 13th century. They are narrative songs, originally styled in quatrains (ballad stanzas). With words/lyrics as a requirement.

From a non-song compositional point of view, poetic ballads (literary ballads) are written in the same style. With words. Robert Burns, Walter Scott, Goethe, Coleridge, Keats, Poe, Wordsworth, Oscar Wilde, Christine Rossetti, Kipling -- all wrote literary ballads. Not surprisingly, each of these poets used words for their ballads.

So, in the sense of an "adagio", you may call it whatever you want beyond "adagio", but it is not a "ballad" in the literary and historical perspective. So no one who has commented thus far is wrong or "unaware" about their selections, per se. In fact, they are using the term in a far more correct  sense than you have.

Angra - Deep Blue (from Holy Land).

And that's just a start of the Pentangle related ones...

In the traditional sense, a ballad is a stanzaed poem or song narrating a story. It may or may not be a love song, but it should tell a story. Therefore, when I hear "ballad" the inner English Major in me kicks in, and I think chanson or canzone. So from a modern sense, I am more apt to think of Bob Dylan singing "The Ballad of Frankie Lee and Judas Priest", "Tangled Up In Blue" or "Hurricane", which are ballads in the truer fashion, and not the trivialized ditties ballads have become. 

From a prog sense of the word, a ballad could be Jethro Tull's "Velvet Green", which recalls the bawdier "Broadside Ballads" of the 17th and 18th centuries...

You mentioned King Crimson's "Book of Saturdays", but you might as well throw in "Cirkus" as as a modern approximation of a ballad as well...
