On any track or album page, click the Share/Embed button and then click the Tumblr button (next to Tweet). That will automatically embed the horizontal player, and it’ll look great in your blog and on Tumblr’s dashboard. It’s possible to embed the standard or small layout player instead, but it will not appear inline in Tumblr’s dashboard view, so we don’t recommend it. If you wish to defy our counsel, you’ll need to go to https://www.tumblr.com/settings and temporarily switch your “Edit posts using” setting from “rich text editor” to “plain text/HTML” (Tumblr’s default rich text editor strips some of the attributes from the iframe tag, which causes the player to clip). Then click the Share/Embed link back on Bandcamp, choose “Embed this album,” and pick the standard or small player.
