It depends on the artist. Much of it is redneck noise.
And to me, much alternative rock is "alienated white boy noise".
Doing the unusual for a person in their 30's, I became a country fan. I'll pay $600 for good seats to see Garth Brooks and welcome Dwight Yoacam and Alan Jacson to local venues just like I do for FGL or Miranda Lambert. So to me, coming from suburban Cleveland, that is neither noise nor particularly redneck, either.
Mark Knopfler, Bob Dylan, Springsteen, and many more are master storytellers. You won't find Radio stations playing their stuff very often.
I saw Bob Dylan at the famous "Desert Trip" 5 years ago. Everyone around us... who had spent a minimum of $600 to see the Rolling Stones, Bob Dylan, Paul McCartney, Neil Young, Roger Waters, and The Who thought that Dylan was dull, boring and had zero connection with the audience.
There's all kinds of genres that commercial Radio ignores. It's not just the Country artists you're talking about...
You can't believe how many kinds of music, songs and artists have been researched over and over and over There is no potentially successful genre or blend sitting out there waiting to be discovered.
While there have been lots of format variants over the years, count the "new" music formats since the 50's... not very many.
1951 started it with Top 40. R&B followed as stations dropped network programming. So did country. The old network stations often became MOR as they dropped soaps and drama. The end of the 60's gave us Beautiful Music, a refinement of soft instrumentals
The late 70's found album rock, which gave us AOR and other variants but none of those was anything but a derivative. 70's brought us Chicken Rock, later called AC. And the old Top 40 lists gave us oldies. For a while, we got disco as a format.
A decade later Beautiful Music gave us Smooth Jazz, and later we got Urban AC, which was really a derivative of Urban (which was a new name for R&B) with the same songs, just older. And Adult Hits was just a broader blend of oldies with a specific genre focus.
Hip hop is a derivative of Urban as are most "unique" newer formats. Even the various Spanish language formats heard in the US are derivatives of traditional Latin American formats... only two truly original Latin formats have been created in the US in the last 50 years, "all salsa" (WZNT) and Spanish adult hits (KRCD).
Yet we've all gone through multiple perceptual tests and focus groups and the like to try to find a formula or blend that will make a difference. There are not, though, "all kinds of genres" that have not been discovered or exploited.
