Amazon has teamed up with IMDB (Internet Movie Database) to launch a Wikipedia-style music information site called SoundUnwound. Users can access all kinds of music-related information and data through SoundUnwound, including details about singers, bands, albums, music genres, and more. Additionally, SoundUnwound allows users to participate in collaborative editing, similar to Wikipedia. However, all edits must be reviewed and approved by Amazon staff to ensure the accuracy of the content.
