I'm obsessed with Spotify and I'm not ashamed to say it. The app is so well designed and I love discovering new music, either through a friend's profile or from the suggestions Spotify sends you. Deep Focus is my go-to playlist when I need to...well...focus. Or quiet my thoughts. New Disco and Tranquility With a Beat are also other favorites. They have some really interesting playlists designed to get you through your day or to enhance your mood. It's definitely worth exploring.
