I'm really not at all keen on John Rutter's music, which puts me in a minority in our choir, I think. I once described it as "Disney in church", to the amusement of our conductor - who I think is inclined to agree with me, but realises that he's not in a position to do so publicly without upsetting other choir members.
Some jazz is very good. It's amazing how Bach invented almost everything that's good about music, and Jacques Loussier milked this well. I think it's the 2-part invention in A minor whose left hand part, in the final 8 bars, is pure jazz - remarkable for a piece written around 1720, give or take a bit.
I don't think there's a great deal of music I really can't stand - unless it's something banal that's played ad nauseam, which I'm afraid tends to apply to a lot of pop music when it in vogue. Something like "The Birdie Song" or "Viva l'Espana" when heard more than once a decade do tend to grate rather. I'm quite capable of totally ignoring a lot of music.
I'm not keen on what (in my ignorance) I'll describe as "Italian-style brass bands" because I know how wonderful some of the colliery/industry bands from Oop Noorth can sound.
If music is good (read Zoltan Kodaly for a definition of what constitutes "good" music) then I think it's very possible to train yourself to like it. I don't think I know anyone who liked beer at the first attempt, but it's worth persevering. When I was doing A level, one of our set works was Bela Bartok's Music for Strings, Percussion and Celeste, which definitely took a lot of getting used to, but I'm a great fan of Bartok now. I think he's my favourite 20th century composer, and I'd sooner listen to his music than that of Stravinsky, say, even though the latter is held in higher regard by most musicians.
I rather like opera, but you have to suspend disbelief for most of the plots, which are utter bollocks. Some of it is absolutely superb, and anyone who remains unmoved by "Soave sia il vento" from Cosi fan Tutte has no soul.
