"Shounen yo, shinwa ni nare" — Boy, become a myth. This 1995 song remains a mandatory karaoke pick for Japanese learners. "Unmei" (fate) and "kagayaku" (shine) are eternal themes in Japanese music.

"Zenzenzense kara boku o sagashi hajimeta" — Since the previous previous previous life, I began searching for you. "Deau" (meet) and "sagasu" (search) are RADWIMPS' core verbs, and cornerstones of Japanese love songs.

YOASOBI's lyrics are famous for "everyday words + unconventional combinations." "Kokoro" (heart) and "shinjiru" (believe) appear in Japanese songs about as often as "love" and "believe" in English songs — you simply can't avoid them.

"Tondara modorenai" — Once you fly away, you can't come back. Nature imagery (sky, wind, birds) is the romantic code of Japanese lyrics. Remember "sora" (sky) and "kaze" (wind), and you'll decode half of all nature-themed songs.
