Linda Hamdan🎧 “MoodMix” — a social mood + music app Think of it like a cross between Spotify, BeReal, and a low-pressure social diary. 💡 Core idea Teens log their mood once or twice a day using quick taps (no long journaling). The app then: Generates a music playlist that matches their vibe Lets them share their “mood snapshot” with friends Shows how their mood changes over time (like emotional stats 📊) 🔥 Why it works No cringe oversharing required Music is already central to teen life Feels personal but still social Could integrate with Spotify or Apple Music later 🧱 Basic MVP Features Select mood (happy, stressed, tired, excited, etc.) Generate a playlist (mocked at first) View mood history Simple social feed (friends’ moods) 🧪 Simple Starter Code (React Native with Expo) This is a basic working prototype UI to get you started: 1. Setup npx create-expo-app MoodMix cd MoodMix npm start 2. Replace App.js with this: import React, { useState } from 'react'; import { StyleSheet, Text, View, TouchableOpacity, FlatList } from 'react-native'; const moods = [ { id: '1', name: '😊 Happy', playlist: ['Sunroof', 'Good as Hell', 'Levitating'] }, { id: '2', name: '😴 Tired', playlist: ['Slow Dancing', 'Location', 'Pink + White'] }, { id: '3', name: '😤 Stressed', playlist: ['Lo-fi Beats', 'Weightless', 'Chill Study'] }, { id: '4', name: '🔥 Hype', playlist: ['SICKO MODE', 'POWER', 'HUMBLE.'] }, ]; export default function App() { const [selectedMood, setSelectedMood] = useState(null); return ( <View style={styles.container}> <Text style={styles.title}>MoodMix 🎧</Text> <Text style={styles.subtitle}>How are you feeling?</Text> <View style={styles.moodContainer}> {moods.map((mood) => ( <TouchableOpacity key={mood.id} style={styles.moodButton} onPress={() => setSelectedMood(mood)} > <Text style={styles.moodText}>{mood.name}</Text> </TouchableOpacity> ))} </View> {selectedMood && ( <View style={styles.playlistContainer}> <Text style={styles.playlistTitle}> Your {selectedMood.name} Playlist: </Text> <FlatList data={selectedMood.playlist} keyExtractor={(item, index) => index.toString()} renderItem={({ item }) => ( <Text style={styles.song}>{item}</Text> )} /> </View> )} </View> ); } const styles = StyleSheet.create({ container: { flex: 1, backgroundColor: '#121212', alignItems: 'center', justifyContent: 'center', padding: 20, }, title: { fontSize: 32, color: '#1DB954', fontWeight: 'bold', marginBottom: 20, }, subtitle: { fontSize: 18, color: 'white', marginBottom: 15, }, moodContainer: { flexDirection: 'row', flexWrap: 'wrap', justifyContent: 'center', }, moodButton: { backgroundColor: '#282828', padding: 10, margin: 8, borderRadius: 10, }, moodText: { color: 'white', fontSize: 16, }, playlistContainer: { marginTop: 20, alignItems: 'center', }, playlistTitle: { color: '#1DB954', fontSize: 18, marginBottom: 10, }, song: { color: 'white', fontSize: 16, marginVertical: 2, }, }); 🚀 Where to take it next If you want to level this up from “cool project” to “people actually use this”: Add login (Firebase 🔐) Save mood history (so users can track patterns) Real music API (Spotify API 🎶) Friend system + mood feed Streaks (teens love streaks more than sleep)

System Requirements
System Requirements Document (SRD)
Project Name: emerald-mood
1. Introduction
Welcome to the System Requirements Document (SRD) for emerald-mood, a web-based extension of the innovative MoodMix concept. This project aims to bring the lightweight, mood-driven music experience to browsers, enabling users to log their moods, generate playlists, and connect socially—all from the convenience of their desktop or mobile web browser.
Linda Hamdan, based in the US, envisions emerald-mood as a platform that resonates with teens by combining emotional self-awareness with music, while maintaining a low-pressure social environment. This document outlines the requirements necessary to bring this vision to life.
2. System Overview
emerald-mood will be a web application designed to complement the existing MoodMix app. It will allow users to:
- Log their mood quickly using intuitive taps.
- Generate music playlists tailored to their emotional state.
- Track their mood history over time.
- Share mood snapshots with friends via a simple social feed.
The platform will leverage modern web technologies to ensure accessibility, responsiveness, and scalability. Integration with music APIs (e.g., Spotify or Apple Music) will be considered for future iterations to enhance the user experience.
3. Functional Requirements
Mood Logging and Playlist Generation
- As a User, I should be able to select my mood from a predefined list of options.
- As a User, I should be able to generate a playlist that matches my selected mood.
Mood History

Social Features
- As a User, I should be able to share my mood snapshot with friends.
- As a User, I should be able to view my friends’ mood snapshots in a simple feed.
Authentication

4. User Personas

- Pain Points: Avoiding oversharing, maintaining privacy, and finding music that matches their mood.
2. Admin

5. Visuals Colors and Theme
Unique Color Palette

- Surface: #1B263B (Soft Navy)
- Text: #E0E1DD (Light Gray)
- Accent: #1DB954 (Spotify Green)

This palette creates a calming yet engaging atmosphere, ideal for mood tracking and music exploration.
6. Signature Design Concept
Interactive Mood Galaxy
The homepage of emerald-mood will feature an Interactive Mood Galaxy—a dynamic, animated visualization where each mood is represented as a glowing star in a constellation.
-
User Interaction:
- Hovering over a star reveals its mood name and associated playlist.
- Clicking on a star zooms into its orbit, displaying mood-specific playlists and stats.
-
Animations:
- Stars pulse gently to simulate a living galaxy.
- When a mood is selected, the galaxy subtly shifts colors to match the mood’s vibe (e.g., warm tones for happy, cool tones for tired).
-
Transitions:
- Smooth zoom-in and zoom-out effects when navigating between moods.
- Micro-interactions like glowing trails when users move their cursor across the galaxy.
This bold design will make the homepage unforgettable, inviting users to explore their emotions in a visually immersive way.
7. Non-Functional Requirements

- Scalability: The system should support up to 100,000 concurrent users.
