Architecting a Modern Music Streaming Platform: Lessons from Building a Spotify Clone

I’ve spent the last few weeks building a high-fidelity Spotify clone using the 2026 tech stack: Next.js 16, Prisma 7, and NextAuth v5.

While most clones focus on the UI "look and feel," my goal was different: I wanted to build a production-ready system that handles real-time music data from the Deezer API while maintaining a performant, type-safe architecture.

The Architectural Challenge

The biggest hurdle in building a media-heavy application isn't the sidebar or the navigation—it’s data normalization. How do you take massive amounts of dynamic API data (artists, albums, songs) and map them into a local relational database without creating a "data bottleneck"?
