Discogs is an online music database and marketplace founded in 2000. It provides an extensive and detailed catalog of recordings, artwork, and artist information. With over 8 million releases, Discogs is the largest physical music database and marketplace in the world. It allows users to catalog, rate, and review recordings and to track their own collection of records. Discogs also allows users to buy and sell music and merchandise, making it a great resource for collectors and music fans alike. The Discogs app allows users to access their Discogs account on the go and manage their collection, as well as search and buy music. Discogs also provides tools for labels and artists to manage their release information and market their music.
Like Discogs, it's a database of music releases, but with a bunch of added social and cataloging features.
