Îmi place genul acesta de muzică.

Romanian uses a plăcea in a structure closer to something is pleasing to me than to English I like something.

So in Îmi place genul acesta de muzică:

• îmi = to me
• place = is pleasing
• genul acesta de muzică = the thing that is pleasing

Literally, the structure is roughly This kind of music is pleasing to me.

This is why Romanian learners of English, and English speakers learning Romanian, often have to mentally switch the sentence structure.

Îmi is the unstressed dative form of eu and means to me.

In this sentence, it marks the person who experiences the liking:

• îmi place = I like / literally it pleases me
• îți place = you like
• îi place = he/she likes

You will also often hear mi place in speech. Both îmi place and mi place are used, with îmi often appearing in more careful or sentence-initial usage.

Because the verb agrees with the thing being liked, not with the person who likes it.

The subject here is genul acesta de muzică, and the head noun is genul, which is singular. So the verb must be singular:

• Îmi place genul acesta de muzică. = singular thing
• Îmi plac genurile acestea de muzică. = plural things

This is one of the most important patterns with a plăcea:

• singular noun -> place
• plural noun -> plac

The -ul is the Romanian definite article, attached to the end of the noun.

So:

• gen = a kind / a genre
• genul = the kind / the genre

In Romanian, when a demonstrative like acesta comes after the noun, the noun is normally definite:

• genul acesta = this kind
• băiatul acesta = this boy
• cartea aceasta = this book

So genul is definite because it is part of the pattern noun + demonstrative.

Yes, you can also say acest gen de muzică.

Romanian allows both patterns:

• genul acesta de muzică
• acest gen de muzică

Both mean the same thing: this kind of music.

The difference is mostly structural:

1. noun + demonstrative

   • genul acesta
   • the noun is definite

2. demonstrative + noun

   • acest gen
   • the noun does not take the definite article

Both are natural. Many learners first notice acest gen, because it looks more similar to English this kind. But genul acesta is also very common and very natural Romanian.

Because acesta agrees with genul, not with muzică.

The main noun in the phrase is genul (kind/type/genre), which is masculine singular.
The phrase de muzică only tells you what kind of thing it is a kind of.

So the agreement is:

• genul acesta -> masculine singular
• not genul această

If the main noun were feminine, then you would use a feminine form:

• muzica aceasta = this music
• cartea aceasta = this book

So the demonstrative always matches the noun it directly modifies.

Here gen means kind, type, or sometimes genre, depending on context.

In genul acesta de muzică, it is best understood as this kind/type of music. Because the topic is music, English might also translate it as this genre of music.

So gen is a flexible noun. It does not always mean only genre in the narrow artistic sense; it can also mean kind or type more generally.

De muzică specifies what sort of gen we are talking about.

Without it, genul acesta just means this kind/type.
Adding de muzică narrows it down to this kind/type of music.

This is a very common Romanian pattern:

• un tip de problemă = a type of problem
• o formă de artă = a form of art
• genul acesta de muzică = this kind of music

So de here works very much like English of.

Because in genul acesta de muzică, muzică is part of a de + noun phrase that describes the type/category.

Romanian often leaves the second noun without an article in this kind of structure:

• o cană de ceai
• un articol de ziar
• un gen de muzică

So muzică is not being presented as the music in a definite sense here. It is naming the category.

If you said de muzica aceasta, that would mean something more like of this music, which is a different and more specific idea.

Both are natural.

• Îmi place acest gen de muzică may feel a little more straightforward to an English speaker because it follows a this + noun pattern.
• Îmi place genul acesta de muzică is also very common and idiomatic Romanian.

In everyday Romanian, both wordings are perfectly acceptable. The choice is often just a matter of style, rhythm, or personal preference rather than a big difference in meaning.
