User Story

As a college-going user, I want to frequently find new songs based on what I've listened to in the past, so that I can expand my music taste without manually searching.

Design Considerations

  • There should be clear navigation to find the playlist on the user profile
  • A notification should remind users of the playlist update
  • An intuitive button should allow for saving songs from the playlist
  • User feedback for individual songs should be incorporated as micro-interactions
  • Special toggles to specify factors the users want to be considered higher when getting recommended a song
  • Lesser known artists and songs should be prioritized higher in the list in a visually appealing manner

Performance Considerations

  • Backend must handle a simultaneous roll-out of playlists every week without crashing
  • Maintain the database with updated statistics on user data and artist metrics on the app
  • The song recommendation algorithm should be optimized based on user feedback, content-based data, and collaborative filtering in the least time complexity possible
  • A cache should be utilized to reduce latency when processing user interactions
  • Performance testing must be conducted to identify issues in scalability and loading times

Security Considerations

  • Encrypt user data in the database to protect from unauthorized access
  • Utilize an authentication system to ensure user access to the tailored playlist
  • Implement measures to prevent hackers from generating the playlist more frequently than the designated time
  • Find system vulnerabilities using regular pen-testing and other corner-case testing

Localization & Accessibility

  • Train the algorithm with a diverse dataset to avoid bias, including factors such as culture, location, language, and artist popularity
  • Incorporate functionalities according to the Web Content Accessibility Guidelines such as voice automation, read-aloud content, and keyboard shortcuts

Acceptance Criteria

  • Given I have an active subscription, when I open the Spotify application, then I should view the personalized playlist first at the start of every week.
  • Given my Discover Weekly playlist, when I view my current playlist, then I should view at least 30 songs across all the languages I am listening to.
  • Given my Discover Weekly playlist, when I listen to each song, then I should be able to distinctly view the save song button.
  • Given my Discover Weekly playlist, when I view my current playlist, then I should be able to change which features have more weightage in recommendations for next week's playlist.
  • Given I have an active subscription, when I listen to the personalized playlist, then I should have all my data securely encrypted.
