친구와 means with a friend here.

와/과 are particles attached to nouns. They can mean with or and, depending on context.

You choose between them by the final sound of the noun:

• 와 after a vowel
• 과 after a consonant

Since 친구 ends in the vowel 우, it becomes 친구와.

Examples:

• 친구와 = with a friend
• 학생과 = with a student

Yes. 와/과 can mean either and or with.

In this sentence, 친구와 노래방에서 ... 불러요 sounds like doing the action together with a friend, so with is the natural translation.

Compare:

• 친구와 영화를 봐요. = I watch a movie with a friend.
• 친구와 가족이 왔어요. = A friend and family came.

So the particle is the same, but the surrounding sentence tells you which meaning fits better.

Because 에서 marks the place where an action happens.

In this sentence, the action is singing, and that action happens at/in the karaoke room, so 에서 is correct.

Basic difference:

• 에 = to, at, in; often for destination, time, or existence
• 에서 = at/in a place where someone does an action

Examples:

• 학교에 가요. = I go to school.
• 학교에서 공부해요. = I study at school.

So:

• 노래방에서 불러요 = sing at the karaoke room

좋아하는 is the verb 좋아하다 (to like) changed into a form that describes a noun.

So:

• 좋아하다 = to like
• 좋아하는 노래 = songs that [someone] likes

This is a very common Korean pattern:

• 먹는 음식 = food that one eats
• 사는 집 = the house where one lives
• 좋아하는 노래 = songs one likes

In English, we often need that or which, but Korean simply puts the describing verb before the noun.

Not exactly.

Literally, 좋아하는 노래 means songs that [someone] likes.

In many everyday situations, English translations use favorite songs because that sounds natural. But if you want to say favorite more explicitly, Korean often uses:

• 가장 좋아하는 노래 = the song(s) one likes the most / favorite song(s)

So:

• 좋아하는 노래 = songs I like / songs you like
• 가장 좋아하는 노래 = favorite song(s), more literally

Korean often leaves out words like my, your, his/her, or even the subject, if they are clear from context.

So 좋아하는 노래 does not literally say my favorite songs. It just says songs [someone] likes.

From context, it is often understood as:

• my favorite songs
• the songs I like

This kind of omission is very normal in Korean.

를 is the object marker. It marks the noun that receives the action of the verb.

Here, the action is 불러요 (sing), and the thing being sung is 노래 (song), so 노래를 is the direct object.

You use:

• 를 after a vowel
• 을 after a consonant

Since 노래 ends in a vowel, it becomes 노래를.

Examples:

• 빵을 먹어요. = I eat bread.
• 노래를 불러요. = I sing a song.

불러요 comes from the dictionary form 부르다 (to sing, to call).

This verb is a 르 irregular verb.

When 부르다 is conjugated into the polite -아요/어요 form, it changes like this:

• 부르다 → 불러요

So it is not 부르어요.

This happens because:

• the 르 changes
• an extra ㄹ is added to the previous syllable
• then -어요 becomes -러요

That gives:

• 부르다 → 불러요

This is a very common point for learners because the final form looks quite different from the dictionary form.

Yes, 불러요 is the polite non-past form, and it often works like the present tense in English.

Depending on context, it can mean:

• I sing
• I am singing
• I will sing

In this sentence, it most naturally sounds like a habitual or general statement:

• I sing songs I like with a friend at karaoke or
• We sing favorite songs at karaoke

Korean often relies on context instead of marking these differences as clearly as English does.

Because Korean very often omits the subject when it is already understood from context.

So the sentence does not explicitly say:

• I
• we
• he/she

It simply says:

• with a friend
• at a karaoke room
• songs [someone] likes
• sing

In a textbook, this is often translated as I sing..., but real Korean frequently leaves the subject unstated if it is obvious from the situation.

Korean and English organize sentences differently.

This sentence is built like this:

• 친구와 = with a friend
• 노래방에서 = at the karaoke room
• 좋아하는 노래를 = songs I like
• 불러요 = sing

So Korean puts the verb at the end, and descriptive parts come before the noun they describe.

A very literal order would be:

• With a friend, at the karaoke room, liked songs, sing.

That sounds strange in English, but it is normal in Korean. This is one of the biggest sentence-structure differences learners notice early on.
