Last year, TikTok partnered with Spotify to allow users who discover favorite music through videos watched directly to the audio streaming platform. Recently, Instagram introduced the same feature.
When you're watching Reels videos on Instagram and listening to cool music, maybe Taylor Swift? You can press the music label displayed on the video, then you will be taken to a page to explore other videos that use the same music – here you will see an icon to add the music directly to Spotify.
You need to give Instagram permission to access your Spotify account to use this feature. For Spotify users and those active on Instagram, this is a useful feature. Only, Instagram is a bit behind because TikTok also offers support for Apple Music and some other audio streaming.
