It didn’t take long for the Internet Movie Database to become a go-to resource on movies, TV shows, directors, actors, writers, etc. It became a subsidiary of Amazon a few years ago, and now the company is trying do for for aural entertainment the same thing it did for the visual.
The new site SoundUnWound is in beta, but plans on being a new wiki-style information source on all things musical, with artist bios, album credits, and song samples. The pages also include YouTube videos, timelines, and lots of cross-referencing. There’s not as much info as on Wikipedia and other sites, but as SoundUnWound grows in popularity, more users will add more info, just as they did to IMdB, and it may become a valuable resource.
