Twitter’s standalone #Music app hasn’t really taken off, so the company is trying again: On Thursday it launched the app on Spotify. The app lets users listen to songs that are trending on Twitter and quickly add them to existing playlists. Users can also turn entire collections from the app (“Emerging,” “Unearthed,” etc.) into new playlists. And because the Twitter app is accessible from Spotify Desktop, users can listen to entire songs (not just snippets) even if they don’t have a Spotify Premium account.
