When Twitter first announced Audio Cards that would put songs in your social feed, SoundCloud was the music service of choice at launch. After the feature has been available for well over a year, Spotify tracks will now show up in a similar fashion. Any tweet that contains a link to a song from the streaming service will offer a 30-second preview in your timeline. Spotify clips will also appear in that curated Moments feed, which is how the company broke the news today.
