I'm going to update open.audio right now to benefit from the new opengraph / embed /oembed features, expect a few minutes of downtime
and we're good!
You can now albums and individual tracks from open.audio into third party website (as long as you can insert an iframe into them and the embedded content is available publicly), as shown in the video below \o/
Linking an artist, album or track page (such as https://open.audio/library/albums/5786) should now generate a preview card on OpenGraph compatible sites (such as Mastodon, Facebook, etc.)
mastodon.eliotberriot.com is one server in the network
