Genius.com

Genius is a website for looking up song lyrics alongside annotations that explain references, meaning, and context, contributed by a community of users and verified artists. It is used by listeners researching songs and by fans discussing lyrics, reaching an audience focused on music.

Annotations can cover wordplay, cultural references, or the story behind a particular line, and artists sometimes contribute their own explanations directly on a song's page.

Its ads.txt file lists 364 authorized ad systems, with 103 direct and 334 reseller entries, reflecting advertising sold largely through resold programmatic partners.
