Is there any quick way to import a release from discogs?
There is. You need to install this userscript to your browser: https://github.com/murdos/musicbrainz-userscripts/blob/master/discogs_importer.user.js
Exactly how will depend on the browser. Chrome, Vivaldi and I think Edge can use Tampermonkey.
or, you can simply copy and paste the tracklist. The other stuff still needs done by hand.
Discogs still lets you do that. Spotify and iTunes have both stopped it.
It gets much more than just the track list. The importer will copy over the label, cat no, country, date, barcode and paste in a link back to the Discogs page
The script is a big time saver, but you need to remember to set a few things like Language. And then Fix All The Capitals That Discogs Will Have Put In.
I find it a massive time saver.
This is a good addition to go with it:
That will let you pick up artwork at higher than 600x600 res from Discogs. I don’t know the quick way to use it as it is a bit more of a multi-purpose artwork tool. I find I need to go into the Edit Release \ Edit Images page, and then click VIEW on each image in turn. That opens separate pages for the artwork which then jump to Full Size ready for saving
