## 🚀 Deployment Steps

1. **Pre-deployment**
   - Run all tests
   - Check environment variables
   - Review database migrations
   - Create deployment branch

2. **Deploy to staging**
   - Test all critical user flows
   - Verify offline functionality
   - Test payment processing
   - Load test with production-like data

3. **Deploy to production**
   - Schedule during low-traffic period
   - Run database migrations
   - Deploy application
   - Verify deployment
   - Monitor error rates

4. **Post-deployment**
   - Smoke test critical features
   - Monitor performance metrics
   - Check error logs
   - Verify CDN cache behavior
   - Test from multiple regions

## 📊 Monitoring Metrics

### Application Health
- Response time (target: <200ms for API, <1s for pages)
- Error rate (target: <0.1%)
- Uptime (target: 99.9%)
- Database connection pool usage

### User Engagement
- Daily/Monthly active users
- Average session duration
- Tracks played per session
- Download conversion rate
- Playlist creation rate

### Performance
- Largest Contentful Paint (LCP): <2.5s
- First Input Delay (FID): <100ms
- Cumulative Layout Shift (CLS): <0.1
- Time to First Byte (TTFB): <600ms

## 🔧 Known Limitations

1. **In-memory rate limiting** - Resets on deployment; consider Redis for production
2. **No email verification** - Users can sign up without email confirmation
3. **Basic search** - No full-text search or fuzzy matching
4. **No payment processing** - Subscription management UI exists but no Stripe integration
5. **No artist payouts** - Earnings tracking exists but no automated payout system

## 📝 Recommended Improvements

### Short-term (1-4 weeks)

### Medium-term (1-3 months)
- Integrate payment processing (Stripe)
- Add artist payout automation
- Implement recommendation algorithm
- Add social sharing features
- Create mobile apps (iOS/Android)

### Long-term (3-6 months)
- Add live radio/streaming
- Implement collaborative playlists
- Add artist analytics dashboard
- Create artist verification program
- Build content discovery algorithm
