"I like classical music."
Translation:Мне нравится классическая музыка.
«Класси́ческая му́зыка» is a nominative case form, used for subjects of the sentence. In sentences with «нравится», «класси́ческая му́зыка» is actually a subject: literally, «мне нра́вится класси́ческая му́зыка» can be understood as 'to-me is-likeable classical music'.
However, «я люблю́» works differently: with «люблю́», the thing you love is an object (just like in English). Objects in Russian have to be put in a different form: accusative case. Accusative case would be «класси́ческую му́зыку»: «Я люблю́ класси́ческую му́зыку».
«Я люблю́» can be said about thinks you have been liking for some time. «Мне нра́виться» can be used for the things you like right when you see them (although there's nothing wrong with using it for things you have been liking for some time).
So, for example, if you hear a song for the first time, you can only say «Мне нра́вится эта пе́сня». But if you have heard this song several times, you can say «Я люблю́ э́ту пе́сню».

An adjective can modify a noun (‘good weather’) or be a predicate (‘weather is good’).
\1. When adjective modifies a noun, its location usually depends on whether it’s declinable. I.e. where it changes its form to match the case, gender and number of the noun.
a. Most adjectives are declinable. Those adjectives go before the noun:
- кра́сный цвет = red colour (it changes its forms: genitive красного цвета, dative красному цвету, etc.)
- большо́й разме́́р = big size (genitive case большо́го разме́ра, dative большо́му разме́ру, etc.)
b. Some adjectives are indeclinable. They don’t change their form to match the case, gender or number of the noun. These go after the noun:
- цвет ха́ки ‘khaki colour’ (it doesn’t change its form: genitive цве́та ха́ки, dative цвету ха́ки, etc.)
This includes the comparative forms:
- разме́р побо́льше = bigger size (genitive разме́ра побо́льше, dative разме́ру побо́льше, etc.)
\2. Predicate is Y in the ‘X is Y’ part of the sentence.
a. When adjective is a predicate, it normally follows the noun:
- Цве́т кра́сный. ‘The colour is red.’
- Разме́р большо́й. ‘The size is big.’
b. The position can be changed if predicate is known information (topic), and the subject is something we’re trying to say:
- Кра́сный цве́т. It’s the colour that is red. The colour is red. (the listener knows that something is red, and you give them new information: it’s the colour)
- Большой разме́р. It’s the size that is big. The size is big.
\3. The word order can be changed for emphasis, especially in poetry and in colloquial speech. Duolingo doesn’t usually give you examples with emphatic word orders, and doesn’t accept it in answers.
Not for the feminine gender. Feminine is the only gender that gets its "own form" of accusative, with "у" or "ю" (or no change, for feminine nouns ending in "ь"), and is always used, animacy of the noun does not matter.
For the other genders (masculine, neuter and plural) the accusative is the same as the nominative (if inanimate) or the same as the genitive (if animate).
I would argue that rock, techno, rap, country, etc., are proper names, so you can name them without adding "music" to them, but with "classical music", you do need it because it's only an adjective by itself. I've never heard anyone saying in Spanish, English, Portuguese, Italian, or French only "classical" (unless by context you were already talking about music, so just saying "classical" would make sense)
The Russian construction is different from the English way of putting it: It would be the object in English, but the Russian construction is "To me pleases itself classical music" or "Classical music makes itself pleasing to me". Мне нравится sounds good in Russian. Translating it literally doesn't sound so good in English!! But Music is the subject. Think of it a bit like the passive in English 'I stroke the cat' (Active) The cat is the object. BUT 'The cat is stroked by me' (Passive). The cat becomes the subject.
