Music discovery is a big part of social media these days. Instagram might be slightly late to the party, but at least, now you can add the songs you hear from posts and Reels straight to your Spotify playlist. If you like a song in a post, tap on the title to go to the audio preview page. You'll know you have the feature if you spot that Add button with the Spotify logo beside the audio scrubber. You will need to link your Spotify account with your Instagram first. But once that is set up, it'll be a one-tap process to add songs to your Liked Songs playlist.
