I dont know. I must seem to listen to the same thing over and over again. (I dont but I guess you could see it that way...)
But I guess I am younger than most classical listeners and haven't had the opportunity to hear all the music that is out there, although I doubt I ever will.
I think I shall tell a little story for you and maybe it will give insight into why I listen to some things a lot:
Since I was maybe five or six years old, I have been hearing classical music, as my dad took a liking to some classical music. He had a period when all he listened to was Pavarotti! and then Yo Yo Ma, then the Berlin Philharmonic, then something completely different like Miles Davis!?! At the time I HATED this music.
When I was ten, I started taking voice lessons, and I was sooo annoyed when I couldn't sing high notes. So I began looking up "high notes" and high songs, and I came across "Der Holle Rache," I looked through the music we have on the computer and found it. So I found the CD it was on and listened to Sumi Jo singing Der Holle Rache, over and over again. That was my first real experience of classical music.
My mum started to get annoyed by me playing it so often, so I listened to the other songs on the CD (It was a collection, Ultimate Opera) and I started to love other songs, like "l'amour est un oiseau rebelle" from carmen, and "ombra mai fu" from Xerses.
Because I liked these songs I decided to look up the opera's they were from. The first opera I heard was Le Nozze Di Figaro, I had a copy of the libretto and I sat for two and a half hours listening to it. Then I looked up other mozart music, and not just his operas!
and that is the story of my life, when I heard new music and I liked it, I would look up the compeser's other works, and see if I had any in my CD or LP collection, then listen to it. And of course in opera, if there is a singer who I thought was very good, like I heard Simionato, I will look for other recordings of that artist, and in that way discover new music and it is the same with ensembles and orchestras, and the conductors who conducted them.
Then really famous works, like Beethovens 3rd, I will look them up, and listen to it. If I think they are good, I will buy them and listen to them more. And if someone recommends a piece, I will listen to it.
But I only ever listen to a piece more than once, if I liked it the first time I heard it, or if I want to compare it to something else.
There are people who listen to the same pieces over and over, because they know that they like that, and that they are unwilling to look up new music. Maybe they are just not that interested in classical music?
To the Duchess:
They type like that, not because they are idiots, but because it is how they write in a non-formal situation. Like in mobile texts and online conversations. It is annoying, especially when they make up abbreviations for words that you don't understand, but surely you understood, 4 meaning for?
It does really really really annoy me though, when people are so "miseducated" that they cant even spell the composer or the instrument or title of the piece correctly. Like : how old was Mowsart when he died?
EDIT:
I think some people are really interested in hearing new music, but most are not. A friend of mine asked if I had any "classic rock" on my ipod, I said yes, so they go through all my songs until they get to Bohemian Rhapsody. (which is a good song but to me as overdone as Canon in D!) I suggest a song and they listen to it for a few seconds, then change it back to bohemian rhapsody. (I think I suggested Tangerine by Led Zeppelin, not that that is important!)
To IceXBeam -
Not every can play Fur Elise, in fact very few people can play more than the first few bars. At my school, it has been banned because teachers were so sick of the first few bars.
