It's an interesting phenomenon on audio forums, posters discussing obscure music almost because it's obscure. Interesting because I, and probably many others as well, have a huge music collection (15,000+ hrs) with little music that I would qualify as obscure; way too much music that is excellent by any standard for me to reasonably listen to almost no matter how long I live (assuming that truly excellent music should be listened to more than once or twice).
Now back to the OP, whatever that was...
My tastes actually have a wide range but there are still a few genres I can do without or take in limited quantities. Along with Morglbl, I also have Yani and John Tesh, Indian Flute music, rock, prog, fusion, jazz, blues, new age, smooth jazz, and yes some singer songwriter, but mor the likes of Michael Hedges.
What I look for in music is more the virtuosity of playing, whatever instrument. Anyone can keep a simple beat on drums, but not like a Gavin Harrison, or Carl Palmer, or Buddy Rich and Gene Krupa. Anyone can strum chords on an acoustic guitar and croon, but play something, again like Michael Hedges. Even with vocals, show some emotion and that your heart is in every word, like Greg Lake, Annie Haslam, Candice Night, even some older Phil Collins before going commercial.
In general, I don't like simple music or songs as much as I like full out playing that takes more than just keeping the beat. I would like to expand my Classical a bit and do like some dreamy Violin and Piano, but I have no idea what to look for or how to sample til I find it.
As for Obscure, 20 years ago when I first joined a message board, I spent a year and a half arguing about cables with all the DBT White Paper guys until I fount the site's Music Forum. It was there I was introduced to Prog. Flower Kings, Marillion, Porcupine Tree as well as so many other types and styles of music I would have never heard. We all traded CD Compilations in Themes, Years, Holidays, and just about anything. My collection expanded by several hundred comps, and then several hundred more purchases of what I liked.
I still trade suggestions with a few guys as well as browsing the Progressive Ears site for hints. I am not mainstream, and don't listen to most mainstream music but I never limit myself to one genre or style. I do like shredding guitar and when it is mixed with a little spirituality as with Phil Keaggy and Glass Harp, it's more interesting. And yes, I also have several Christian Rock comps and disks for Sunday Mornings, but most more spiritual than religious.
I would never tell someone they should or should not like something, all the choices is what makes life so grand, as well as complicated.
