Paste the embed sub-code or link of the Spotify embed as a Tumblr post by pasting the written code in the HTML editor. This will enable your followers to play music as a direct result of your post.
Totally easy just grab the Embed link from Spotify (Share → Embed), paste it into a Text post on Tumblr, switch to HTML mode, and hit publish, Tumblr handles the rest like a champ.
