Do you know what “earworm effect” is? Experience it while you learn languages with catchy music and lyrics that you just can't get out of your head. This highly effective award-winning learning technique uses music as the medium to transport words and phrases of a foreign language into your long-term memory. Start your language learning now! Learn Spanish, French, Portuguese, German, Italian, Mandarin, Japanese, Brazilian Portuguese, Maltese, Dutch, Greek, Russian, Arabic, or Turkish and improve your vocabulary and grammar using the power of music. Earworms plant the words of a foreign language into your head with easy language courses. Try our language learning with music lyrics demo for free. THE EARWOMS METHOD 1. Brain-based: The Earworms method not only provides the words, phrases and grammar that you need for language learning, it also actively anchors them into the auditory cortex of your brain! It’s much more than language courses, it's language learning! Learn French, Spanish, English, Italian, German or Dutch listening to music lyrics. 2. Music is the key: Using music as the medium to learn languages is not only fun, it is also effective. Firstly, music puts the learner into the optimum state of consciousness for learning different languages. Secondly, music lyrics learning allows repetition (a prerequisite for language learning). On top of that, music engages and stimulates both hemispheres of the brain, unleashing more learning potential. 3. Chunking: Instead of language learning in terms of individual words and grammar, the Earworms approach immerses the learner in real-life dialogues and expressions with lyrics. These are broken down into bite-size chunks, practiced rhythmically with music and then reconstructed into full sentences. This gives the learner a strong sense of how real language courses are constructed and learning French, Spanish, German, Italian, English and other different languages and their vocabulary becomes easy. IMPORTANT FEATURES * Developed by language teaching experts. * Convenient. 6-9 minute tracks. Listen and learn track by track, any time, anywhere. * Audio-visual experience with 'karaoke-like' live lyrics feature. * Specific unambiguous goals. 200+ optimally selected sets of words and phrases for language learning. * Measurable. Easy tracking of progress of your language courses. * Target language spoken by native speakers - so correct pronunciation is acquired automatically. * Relevant. Carefully chosen content-rich language. Based on the CEF (Common European Framework) and immediately useful to the learner. * Time-bound. The musical memory method enables real rapid progress. E.g. you can learn to count up to 999 in Mandarin in an hour (!) or retain and recall words, phrases and structures in one language level within a couple of weeks. * Educational discounts are available.

Verdict

The call

The clearest difference is ads: Earworms at none against Duolingo's shown. Earworms also leads on iOS requirement (12.4 vs 17.0). Duolingo's advantage is update cadence (weekly vs every 5 months) and ratings volume (5.5M vs 357). On price, rating, review sentiment and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and Earworms sells 16 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for Duolingo against 4.8 for Earworms.

Written reviews are what separate them: 65% of Duolingo's written reviews are positive against 71% of Earworms's.

UpkeepUpdate frequency

Duolingo ships an update weekly, Earworms every 5 months. The most recent releases landed on September 24, 2026 and September 19, 2026 respectively.
