Ese tipo de música me ayuda a desconectar después del trabajo.

Because ese agrees with tipo, not with música.

In ese tipo de música, the main noun is tipo (type/kind), and tipo is masculine. So you say:

• ese tipo de música
• ese tipo de comida
• ese tipo de película

Even though música, comida, and película are feminine, the demonstrative matches tipo.

Not here.

Tipo can mean guy/bloke in some contexts, for example Ese tipo es simpático = That guy is nice.

But in tipo de + noun, it means type/kind of:

• un tipo de coche = a type of car
• ese tipo de música = that kind of music

So here it definitely means type, not guy.

It means type of music, kind of music, or sometimes style of music, depending on context.

So ese tipo de música is a very natural way to say:

• that kind of music
• that type of music

It is a very common Spanish structure:

• tipo de problema = kind of problem
• tipo de persona = kind of person
• tipo de película = kind of film

Because Spanish uses de in this pattern just like English uses of in type of music.

So the structure is:

tipo de + noun

Examples:

• una taza de café = a cup of coffee
• una clase de español = a Spanish class
• un tipo de música = a type of music

It is just the normal linking word in this construction.

Me means me in helps me.

In Spanish, object pronouns usually go before a conjugated verb:

• me ayuda = helps me
• te ayuda = helps you
• nos ayuda = helps us

So:

Ese tipo de música me ayuda...
literally follows the Spanish pattern That type of music me helps..., but in natural English we say That type of music helps me...

Because ayudar is commonly followed by a + infinitive when you say what something helps someone do.

So the pattern is:

ayudar a + infinitive

Examples:

• me ayuda a dormir = it helps me sleep
• te ayuda a estudiar = it helps you study
• nos ayuda a relajarnos = it helps us relax

So:

me ayuda a desconectar = it helps me switch off / unwind

That a is part of the normal structure after ayudar.

Here it is figurative.

Literally, desconectar means to disconnect, to unplug, or to cut off a connection.

But in Spain, it is also very commonly used to mean:

• to switch off mentally
• to unwind
• to disconnect from stress
• to stop thinking about work or problems

So in this sentence, desconectar is not about cables or machines. It means something like unwind mentally after work.

Because de + el contracts to del.

So:

• de el → del
• a el → al

That is why you get:

después del trabajo

not después de el trabajo

This is a standard contraction in Spanish.

Because Spanish often uses the definite article where English does not.

In English, we naturally say:

• after work
• before school
• at home

In Spanish, it is often more natural to say:

• después del trabajo
• antes del colegio
• en casa (this one has no article, so it depends on the expression)

So después del trabajo is the normal, idiomatic Spanish way to say after work.

Yes, and it would be natural.

Compare:

• después del trabajo = after work / after the workday
• después de trabajar = after working / after I work / after having worked

Both are fine, but they are slightly different in feel:

• después del trabajo sounds more like the everyday routine: after work
• después de trabajar focuses more on the action of working

The original sentence sounds very natural for everyday Spanish.

Yes, Spanish word order is more flexible than English, but the original order is the most neutral and natural:

Ese tipo de música me ayuda a desconectar después del trabajo.

You could also say:

• Después del trabajo, ese tipo de música me ayuda a desconectar.

That puts more emphasis on after work.

The original version is probably the best default word order for a learner.

The accent marks show where the stress goes.

• música is stressed on the first syllable: MÚ-si-ca
• después is stressed on the last syllable: des-PUÉS

Without the accent marks, the stress would follow the normal spelling rules and be pronounced differently.

So the accents are there to show the correct pronunciation.

Yes.

The subject is Ese tipo de música = That kind of music.

What does it do? It me ayuda a desconectar después del trabajo = helps me unwind after work.

So the sentence breaks down like this:

• Ese tipo de música = subject
• me ayuda = helps me
• a desconectar = to switch off / unwind
• después del trabajo = after work

That structure is very typical and useful to copy in your own sentences.
