System Requirements Document (SRD)

Project Name: venus-music

1. Introduction

The venus-music project is a full-stack music streaming web application designed to deliver a seamless and modern music listening experience. Inspired by platforms like Spotify, this application will feature a sleek dark-themed UI, advanced playback functionalities, and integration with external APIs for music streaming.

This document outlines the system requirements for venus-music, ensuring clarity and alignment with the project's goals. The application will cater to users in India (IN), with locale-specific considerations such as time zones (IST) and currency (₹) where applicable.

2. System Overview

The venus-music application will provide users with the ability to stream music, create playlists, like songs, and explore trending tracks. The system will consist of:

• A frontend built with React.js for a responsive and interactive user interface.
• A backend powered by Python (FastAPI) for robust API handling and integration with external music streaming APIs (YouTube and Spotify).
• A database to store user profiles, playlists, and metadata for seamless user experience.

The system will integrate YouTube and Spotify APIs for music streaming, ensuring access to a vast library of songs without the need for local song storage.

3. Functional Requirements

• I should be able to sign up and log in securely.
• I should be able to search for songs, artists, and playlists.
• I should be able to stream songs via YouTube or Spotify APIs.
• I should be able to create and manage playlists.
• I should be able to like and unlike songs.
• I should be able to view recently played songs.
• I should be able to see trending songs and recommendations based on my liked songs.

As an Admin:

• I should be able to manage user accounts.
• I should be able to monitor API usage and system performance.

4. User Personas

6. Signature Design Concept

Interactive Galaxy Music Map

The homepage of venus-music will feature an interactive galaxy map where each star represents a song, artist, or playlist.

• Visuals: A dark, starry background with glowing, animated stars.
• Interaction: Hovering over a star will display a tooltip with the song/artist/playlist name. Clicking on a star will open a modal with detailed information and playback options.
• Animations: Smooth zoom-in and zoom-out transitions as users navigate the galaxy. Stars will subtly pulse to indicate activity.
• Micro-interactions: When a song is playing, its corresponding star will emit a glowing ripple effect.

This concept will make the homepage visually captivating and provide a unique way for users to discover music.

7. Non-Functional Requirements

• Performance: The system should handle up to 10,000 concurrent users with minimal latency.
• Scalability: The backend should support horizontal scaling to accommodate growing user bases.
• Security: All sensitive data must be encrypted, and APIs must be protected with authentication and rate limiting.
• Availability: The system should maintain 99.9% uptime.
• Localization: The application should support Indian time zones (IST) and currency (₹) for any future premium features.
