Spotify has rolled out a new feature called “User Notes,” allowing listeners to add custom annotations to tracks within their playlists. The User Notes feature is currently available to both Free and Premium account holders aged 16 and older in select markets, with availability expanding gradually. Alongside this release, Spotify also introduced a separate AI-powered feature focused on fitness tracking. The smart running mode curates audio playback by analyzing the user’s music preferences, running cadence, and different workout phases to automatically match track tempos to exercise intensity. Unlike User Notes, this feature is restricted exclusively to Spotify Premium subscribers in designated regions.
