I've never been a fan of Wagner, too Romantic-going-on-impressionism for me.
I am more of a ... traditionalist, give me Brahms, Bach, Beethoven (who shows great exploration and non-conformity while remaining structuralist, so to speak). Even Beethoven's most wild pieces (the famous and great, love-it-or-hate-it Grose Fuge, for example) are structuralist.
I somehow never manage to be moved by Stravinsky, and much less by Wagner. Full-on Expressionism such as Schoenberg definitely takes me somewhere when I pay attention to it, but it is far from being my favorite. Wagner makes me feel bored every single time I listen to it. It is not lack of concentration or interest as I sit through Beethoven symphonies or Haydn sonatas just concentrating on the movements in the music. Even if I take the approach of listening to Wagner as I listen to Burzum (letting it wash over me and just "ride the tide" werever this stream takes me) I do not feel any pull, I don't feel like I am being lead anywhere.
I will still listen to your shared Tristan and Isolde, though.
