들으면 does indeed come from 듣다+(으)면. When a ㄷ is before a ㅇ, it changes to ㄹ. Ex. 걷다 (to walk) in the present tense is 걸어요. 들으면 - If I listen (If can be translated as "when" but "if" is more accurate. Also, in English there is only one word for "when". In Korean, there are two and you have both in that sentence (으)면 & (으)ㄹ 때. Using "if" should avoid confusion) 생각 - thought, thinking, idea 생각하다 - to think 나다 - to grow, sprout; to happen, break out; to occur, cross (one's) mind 생각이 나다 - to have an idea come up, recall, remember It means "IF I listen to a Blur song, (then) I recall WHEN I was a middle school student." More naturally, "When I listen to Blur songs, I think of when I was a middle schooler." 지금 블러의 노래를 들으면 중학생 때가 생각이 나요. When I listen to a song by Blur, I think of the times when I was a middle school student. It does mean that "if 블러의 노래를 듣다 then 중학생 때가 생각이 나다" ? Please explain this "if/then" construction and give me a few more examples so I can learn how to use it. I'm really tired. Sorry. I will help you more tomorrow :)

***GRAMMAR/USAGE NOTE : When the subjects of the first and second clauses are different, the particle following the subject of the first clause changes from 은/는 to 이/가. So even when we would translate it as "when" in English, we use it to mean more than one thing. And one of those things is not what 으면 actually means. It's easier to remember it as "if". There are many ways to translate these sentences into English, but the true meaning denoted in the Korean sentence is always the same. Think in Korean, not English. Was this okay? Do you need more examples?

1. 가) 주말에 보통 뭐 해요? What do you usually do on the weekend? 나) 날씨가 좋으면 등산을 해요. 그렇지만 비나 눈이 오면 집에서 텔레비전을 봐요. If the weather's nice, (then) I go hiking. But if it rains or snows, (then) I watch TV at home. 2. 가) 결혼하면 어디에서 살 거예요? Where will you live once you get married? (If you get married, [then] where will you live?) 나) 회사 근처 아파트에서 살려고 해요.

(Your eyes hurt when you spend too much time on the computer.) The future tense tense isn't used here in Korean but translating it to English we might use "will" even though it's present tense in the original language. Focus on meaning when learning a language - not translating. 4. 나는 기분이 좋으면 춤을 춰요. If I'm feeling good/in a good mood, (then) I dance. (I dance when I'm in a good mood.)
