The style guide is an informative collection of descriptions of musical styles as captured in the Genre and Style fields in Discogs release data. Use the navigation links above to browse pages describing the valid styles for each genre. Also feel free to log in and edit whatever needs corrections, clarifications, or additional info.

We used to have a single place in the old Trac ticket system where style requests were collected. There is no equivalent ticket in Disbugs. Don't create one. We also used to use Discogs Development forum threads for style proposals. This post put an end to both practices and said to use the wiki from now on. However, discussion is more visible and easier to carry out in the forums, so the ADDING NEW GENRES sticky thread in the Discogs General forum was used for a while. That thread was locked in August 2008. People are still using the Adding/Updating Information forum for discussing proposals as well.
What do you do in the meantime? See the post where nik says "For the moment, if you can't find the style, just enter the genre."
