Please don't give up !!! Keep on listening to new things : Liszt, Ravel, Rachmaninov, Scriabin, Bartok and so on. Let your ears get used to different sounds. Also listen other things than piano : symphonic music, chamber music, jazz. I promise you : you will like it.
"You can't like something without learning it and you can't learn something without liking it." (Samson François)
I don't agree
Music is so instinctive that you don't need to learn anything to like it
Either you like or you don't
A famous artist once said that art is also the ability to turn something complicated into something that anyone can identify with immediately, children or laymen alike
Great painters of the past didn't want people to learn anything about paiting history and theory to appreciate their work, they would have considered it a failure on their part, they actually wanted people to appreciate their works using ther instinct not their conscious knowledge and this meant to them their work was a success and that they managed to create art turning complex theory in something immediate and intuitive
Today there's this habit of telling people when they don't like a concert or a symphony or a sonata to keep hearing it until their will appreciate it
But this was considered like cheating
Composers like Rimsky-Korsakov, Tchaikovsky, Grieg, Debussy and others (but I'm sure of these ones) said they really liked a piece of music only if it was appreciated by them after the first or max second listening, if they needed to listen it hundreds of times before they could like it, they considered it worthloss or not something they really liked
Hearing something hundreds of times before you can say that you like it is indeed cheating as even something you would consider horrible would become something you appreciate if you keep hearing it, because of addiction of the mind
Even something painful as pinching you with a sharp knife would become normal after hundred or repetitions and you would even burn to death without feeling pain if you keep gradually increasing the temperature around you
The mind and body can get accustumed to anything
Liking music by getting accustumed to it is cheating, because music is instinctive and immediate that it loses its meaning and its magic if you need to get accustumed to it after lot of repetitive listening
Only music you like after the first listening or the second one is music you can really say you like, all the rest is just psychological accustuming to a umpleasant stimulus
Anyway, there's nothing to undertand when listening to music: either you like or don't, either it means something to you or don't, either the sounds are pleasant to the ear anatomy or don't
You lose the music power if you think while you listen to it, you don't have to understand music just let it happen and be passive while it goes within you
I don't know if anyone is famialiar with Herbert Benson concept of "Relaxation Response" or awareness and wholeness or alpha waves
Music should be listened passively, in complete relaxation with no other thoughts popping out on your head, with your eyes closed and your annoying interior voice shut
You can't experience music the way it should experience if you start thinking about the melodic line, the progressions, the instruments utilized, the speed or if you're distracted by thoughts about your life, what you'll have for dinner, what you'll do Saturday night
Experience it, that's all
Liszt Hungarian Rhapsodies are based on popular Romanian music (for some strange reason Liszt believed it to be Hungarian music) so maybe something that can help you understand the nature of this music is to close your music, wipe your mind of any other though and feel the sensation of East Europe gypsy music let the music draw for you images of paesan dancing or else let the music draw for you the image of life in Bucarest, it's houses and parks
