When browsing Discogs do you find yourself wondering if this on Bandcamp, if can I buy it on Deepdiscount, or what is the Steve Hoffman forum consensus on the best pressing? This is for you.

With the tampermonkey extension for Chrome installed, click the "Raw" button on this gist and it should install this script. Here it is in action:

I decided to have all searches land on Duckduckgo result pages because, as much as I like and use !bang searches, these rely on the search capabilities of the individual sites, which are rarely as good as DDG itself.

New feature a total time row in track listings (when tracks have times listed)

PLEASE NOTE I changed the name to "Discogs Extras" so you may need to uninstall "Discogs Search Extras" script before adding this updated version.
