The way Scala works is simple. All you have to do is swipe left or right if you do or don't like a song that appears on the screen. The way it works is similar to apps for matching up people like Tinder and, in this case, you can score your options by tapping on a sad or a happy emoji.
On the other hand, you also have the option to directly mark songs you want to add to playlists, and these will continually be updated as you rate the songs that show up for you. You can also tap on the album cover to have the app show you information about the album the song is from.
Creating your own custom playlists on Spotify just got a whole lot easier thanks to Scala. With its intuitive system for detecting the songs you'll like, you can easily put together hours of music based on your own personal preferences.
