Music Expert - AI Evaluation & Annotation (Generative Music)

Mercor is hiring music evaluators and annotators

for a frontier generative-music AI lab - from sharp everyday listeners to professional musicians and audio specialists.

Depending on your background, you'll work on one of these:

-

Music evaluation - all levels welcome (including non-musicians with a great ear):

given two AI-generated songs for the same prompt, judge which is stronger on specific questions (overall quality, instruction-following, musical composition, production/artifacts, vocals & lyric delivery, consistency start-to-finish) and explain each choice in a few sentences.

-

Music captioning - professional musicians:

write detailed, technical descriptions of a track (key, tempo, time signature, instrumentation, structure, harmony, production).

-

Lyric timing - native speakers with subtitle/karaoke/transcription experience:

word-by-word timing of lyrics to audio.

You're a fit if you

have a strong, discerning ear and can clearly justify your judgments. Formal music training, production/engineering experience, or multilingual fluency are pluses that route you to specific work.

Details:

Remote • flexible hours • short calibration before staffing • background check + confidentiality agreement required. Genres to start: pop, hip-hop, rock, electronic.
