I agree. Music is uncountable. I think I can recall exactly one time where I heard "one of the musics," in a Beatles documentary. Very strange. So maybe it's colloquial?
As a native english speaker, I wouldn't even say "I don't like such music", even though duolingo says that's an acceptable answer. People will still understand what you are trying to say, but it's just not a common thing to say in my opinion. It could be a common thing to say in British english though, what I said refers to American english.
Yeah, even in British, "such" in this kind of sentence seems to be falling out of favour.
It's correct but it's commonly used in conversation. The "such" is often dropped. It is a bit superfluous. It is often implied and often considered unnecessary since we know what one means when you say "i don't like this music."
I don't think so - "music is", not "music are". What it is, it's uncountable. We don't say "one music, two musics..."
Apparently, it's weird. This is what I'd say in English, it doesn't really make sense to me to say 'I don't like such music.'
The problem with "this music" is ambiguity. Suppose one enjoys a particular style of music, but simply not the particular composition or rendition referenced by the statement. Though I generally hear the phrase "this [kind/sort] of music", "such music" is also a valid phrase.
It might be valid, but no one says it. We seldom use the word "such" and never in this context. "He's such an idiot" would be a joke about him. "There is no such thing" would be one of the few uses of the word.
"I don't like such music" is a type of construction you would hear from a speaker who is new to English (it is really old-fashioned). Instead, consider constructions like "I don't like music like this", "I don't like this kind of music," or even "I don't like this music"
"This" - implies the music is being observed at the moment. But when simply talking about music, you'd say "that kind of music". Saying, "such music" is ok and is normally paired with dislike....but can be perceived as being high-nose or judgemental.
