지금까지 means until now, up to now, or so far.

In this sentence, it sets the time frame as from some point in the past up to the present. It does not just mean now; it emphasizes everything that has happened leading up to now.

So it gives the sentence a sense like:

• so far
• up to this point
• until now

의 marks a relationship similar to 's or of in English.

So:

• 이 밴드 = this band
• 이 밴드의 노래 = this band’s songs / the songs of this band

It shows that the songs belong to or are associated with the band.

In everyday Korean, 의 is sometimes omitted when the meaning is still clear, but in a phrase like this, keeping it is very natural and clear.

Korean nouns usually do not have to show singular vs. plural the way English does.

So 노래 can mean:

• a song
• songs
• music/songs in general

In this sentence, it naturally refers to the band’s songs in general, so English often translates it as songs.

You could add a plural marker like 노래들, but that is usually unnecessary here.

를 is the object marker. It marks 노래 as the thing being listened to.

So:

• 노래를 들었어 = (I) listened to songs

Korean often marks the direct object this way:

• 책을 읽었어 = I read a book
• 영화를 봤어 = I watched a movie

In casual speech, object markers are sometimes dropped, but using 를 is completely standard and often clearer.

자주 means often or frequently.

It is an adverb, so it modifies the verb 들었어.

In Korean, adverbs like this usually go before the verb, so:

• 노래를 자주 들었어

That is very natural word order. Korean word order is somewhat flexible, but putting 자주 before the verb is the most common pattern.

들어 is present/non-past casual speech, while 들었어 is past tense casual speech.

So:

• 들어 = listen / am listening / listen to depending on context
• 들었어 = listened

Because this sentence talks about what has happened up to now, Korean uses the past form 들었어 to describe that past experience or repeated action.

Even though English may use have listened, Korean often uses the simple past form in this kind of situation.

This is a very common thing for English speakers to wonder about.

In English, so far often goes with the present perfect:

• I have listened to this band’s songs a lot so far.

But Korean does not have a direct one-to-one equivalent of the English present perfect. Instead, Korean often uses the past tense to talk about experiences or repeated actions that have happened up to the present.

So 지금까지 ... 들었어 is natural Korean.

The idea is:

• from the past
• up to now
• this has happened repeatedly

It suggests repeated listening over time, not just one single listening event.

There are two main clues:

• 지금까지 = up to now / so far
• 자주 = often

Together, they show that the speaker has often listened to this band’s songs over a period of time.

So the sentence has a kind of habit/experience up to now feeling.

들었어 is in casual, informal speech called 반말.

It is used with:

• close friends
• younger people
• someone you are socially allowed to speak casually to

If you wanted to make it polite, you could say:

• 지금까지 이 밴드의 노래를 자주 들었어요.

A more formal version would be:

• 지금까지 이 밴드의 노래를 자주 들었습니다.

This happens because 듣다 is a ㄷ irregular verb.

The dictionary form is:

• 듣다 = to listen

When a vowel-initial ending is added, the ㄷ changes to ㄹ:

• 듣 + 어 → 들어
• 듣 + 었어 → 들었어

So the stem changes from 듣- to 들- before endings like -어, -었어, and similar forms.

This is why:

• 듣다
• 들어
• 들었어

all belong to the same verb.

Yes. Korean often omits the subject when it is clear from context.

This sentence does not explicitly say I, but in many situations it naturally means:

• I have often listened to this band’s songs so far

If needed, you could add the subject:

• 나는 지금까지 이 밴드의 노래를 자주 들었어.

But Korean usually leaves it out unless it needs emphasis or contrast.

Yes, it can sometimes carry that kind of nuance depending on context.

By itself, 지금까지 just means until now / so far. But in real conversation, it can sometimes suggest:

• up to now, that has been the case
• and maybe something different may happen after this point

For example, if someone continues speaking, they might say something like:

• 지금까지 이 밴드의 노래를 자주 들었어. 그런데 요즘은 잘 안 들어.
  • I used to listen to this band’s songs a lot up to now / until recently, but these days I don’t really listen anymore.

So the exact nuance depends on what comes before or after.

Yes, 들어왔어 can be possible, but it adds a slightly different nuance.

• 들었어 = a natural statement that this happened often up to now
• 들어왔어 = emphasizes that the action has continued from the past until now

So 들어왔어 feels a bit more explicitly like:

• I’ve been listening to this band’s songs a lot up to now

Meanwhile, 들었어 is simpler and very natural in everyday Korean.

The core dictionary form would be based on 듣다.

A more neutral written-style version could be:

• 지금까지 이 밴드의 노래를 자주 들었다.

This is not the same as the dictionary form, but it is the plain written declarative style.

If you want the actual dictionary form of the verb phrase, it would be:

• 지금까지 이 밴드의 노래를 자주 듣다

But that is not a normal finished sentence by itself in conversation. The original 들었어 is a complete casual spoken sentence.
