Music Audio Expert - Spanish (MX) | $3.72-$9.86 One-Time Remote
Overview
Mercor is partnering with a top AI lab to bring experienced music professionals into the loop for evaluating generative music models. This remote, task-based role focuses on assessing AI-generated tracks in Spanish and English, with an emphasis on Mexican Spanish-language music. Your ratings and annotations will directly shape how AI systems understand musicality, creativity, and production quality. The work is flexible — you can put in 10+ hours per week on a schedule that works for you, with pay tied to completed evaluations.
What You'll Do4
- 1Compare AI-generated music samples side-by-side and score them on musical appeal, originality, how well they match the prompt, vocal clarity, and overall mix quality.
- 2Tag and classify each track using a structured system — identifying genre, sub-genre, song structure, vocal style, and instrumentation.
- 3Check AI-generated lyrics and vocal deliveries against reference recordings for accuracy and emotional impact.
- 4Judge the quality of the musical datasets used to train the models, flagging weak or biased examples.
Requirements4
- 1Native or near-native Spanish fluency plus the ability to follow detailed instructions written in English.
- 2At least a semi-professional background in music, demonstrated through either a production track (3+ years as a producer, audio engineer, or mixer with strong mixing vocabulary) or a music-and-language track (deep knowledge of the Mexican Spanish-language music scene as a songwriter, lyricist, performer, composer, or journalist).
- 3Access to quality headphones or studio monitors for careful listening.
- 4Bonus: formal music training, released Spanish-language music credits, or broad familiarity with contemporary Mexican genres.
Who Should Apply
You're a music professional who cares deeply about how AI is reshaping music creation. You have sharp ears, a strong command of Spanish and English, and you can articulate why one mix feels more polished than another. Whether your background is in the studio or in the world of Mexican Spanish-language songwriting, you're comfortable making detailed creative judgments and working independently with clear guidelines.
Salary Insight
Pay is per completed task and varies by task type — the posted average is $3.72–$9.86 per task, with longer evaluation tasks paying more. If you deliver more tasks each week, you move into a higher rate band. This role is not hourly; you're paid only for evaluations that pass quality review.

Application Tip
Before you apply, prepare a few examples of songs you've analyzed — what you noticed about the production, arrangement, or lyrics, and how you'd describe it in Spanish and English. This will help you nail the 25-minute conversational interview and show you can articulate your musical judgments clearly.
