If I go to https://open.spotify.com/ in the web viewer, after completing my login, I can search songs and browse Spotify site, but the play button does nothing. The developers console shows no error or clues either. Other sites with embedded media work (Youtube, Bandcamp, Soundcloud)
I’m aware of the existence of Spotify plugins for Obsidian, but I would prefer to access the original Spotify web player.
Additional info. Using the “share” button on Spotify, it is possible to get the code for an iframe to embed that in any Obsidian note. The Iframe renders a mini-player which works, so it is not an issue of codecs or audio problems. Unfortunately the iframe generated via “share” provides only a demo of the song, a few seconds, and does not allow for login.
