About Think Songs
Lyrics in perfect sync — any song, any device. The lyrics fill in with the music one character at a time: not just at the start of each line, but right on the character being sung. Even when the words are hard to catch by ear, you can see what is being sung. Perfect sync is what Think Songs cares about above all. ■ Perfect sync, above all ・Timings for every character, down to 1/100 of a second ・Long tones keep filling as they are held, and staccato stops the fill between notes (each character can carry both where the singing starts and where it ends) ・The sync offset is remembered for each output — wired, Bluetooth, AirPlay, car audio — so switching devices does not mean adjusting again ・Sync Calibration lines the lyrics up with your setup before you start ■ Show over other apps Put the lyrics in a small window that floats over your other apps. While you reply to a message or look something up, the lyrics keep filling in, in perfect sync with the music. ・Show 2 to 4 lines ・During a long intro or interlude, the next line to be sung appears early, so you can read it before the singing starts ■ Furigana, so anyone can read along Kanji carry furigana, and the furigana fill in character by character too, so you can follow where the song is even over kanji you cannot read. ■ Harmony and unison, at a glance When several people sing, colour shows who sings what. Unison blends the part colours into one; harmony colours the characters in upper and lower bands. ■ Make your own Listen to the songs you already have and stamp timings as you go — character by character, or line by line. Automatic furigana, detection of timings that run backwards, and copying a chorus you have already timed take the tedium out of it. Finished lyrics can be shared on think-songs.com. ■ For people learning Japanese Romaji can be shown too. Tap a word in the lyrics for its English meaning from the bundled Japanese-English dictionary, with an example sentence for many words (works offline). ■ Also ・Works with songs in your device's music library ・Lines wrap at phrase boundaries, never in the middle of a meaning ・Choose the typeface, background, text size and how the lyrics scroll ・Soften the vocals or change the key (unprotected audio only) ・Reads and writes LRC and ALRC files The bundled Japanese-English dictionary is derived from EDICT2 by the Electronic Dictionary Research and Development Group (EDRDG), used under CC BY-SA 4.0. Example sentences come from the Tanaka Corpus maintained by the Tatoeba Project, used under CC BY 2.0 FR. Attribution is shown in Settings > About.

What’s new
Version 1.1.0 · Updated October 23, 2026
Introducing Think Songs Premium. ■ Think Songs Premium A monthly subscription that shows the lyrics of every JASRAC- and NexTone-licensed song in full, to the very end. ・Without a subscription, up to 3 licensed songs a day are shown in full. After that, licensed songs are shown line by line from just before the chorus ・There are two plans: Premium, and Diamond for those who want to support development. The features are the same; only the amount differs. Diamond comes with a supporter badge ・New subscribers can try it free for 2 weeks (if eligible) ・The subscription unlocks lyrics only. Audio for licensed songs is not distributed; songs without audio are added as lyrics only, and the app lets you know ・Subscribing requires sign-in (the subscription is linked to your account). Subscribe, manage and restore purchases under Library > Account ■ New coloring style: Spark Each character changes color and glows at the moment it is sung. A kanji with furigana lights up each time its reading moves on, and English lights up word by word. Choose it under Display Settings (Color/Font/Effects) > Lyric Coloring Style. The preview in Settings now plays in the style you choose. ■ Overlapping voices on one row In call-and-response lyrics where voices overlap, a line can now sit on the same row as the previous one, each filling in at its own timing. In the timing editor, tap "&" at the start of a line to join it to the previous line. ■ Update notice When a new version is available, the Library lets you know. ■ Shared links When you open a song link, "Loading song…" now appears small next to the song title instead of covering the middle of the screen, so you can keep reading the lyrics and using the app while it loads. ■ Other fixes ・Fixed a slight offset between the sound and the lyrics at the start of songs with a vocal track when playing at a speed other than 1× ・Fixed tall background images spilling over the top and bottom of the Lyrics screen and covering the artist name ・Lyrics files that contain newer header fields are now shown instead of failing to load ・Fixed some kana words showing the meaning of a different word in the dictionary (for example, きみ showing "egg yolk")
