How I built PlaySwap with v0 and vibe coding

A while ago, I was a loyal Spotify user. My playlists were carefully crafted, full of bangers for every imaginable mood. But eventually, for convenience (and because I was already paying for YouTube Premium), I switched to YouTube Music.

All good... except for one tiny problem:
Where are my playlists?

I thought: "There must be a tool to migrate playlists from Spotify to YouTube Music, right?"
But instead of searching for something that already exists, I remembered something way more fun:
vibe coding + v0.dev.

So I said: "Why not just build it myself?" 🧪

First steps: from chaos to MVP

The idea was simple — move playlists between platforms.
Using v0 was magical. After just a couple of iterations, I had a working MVP.
A few more tweaks and the UI looked chef’s kiss — clean, modern, and professional.

I felt like a pharaoh giving commands to a digital servant:
"Build me a UI worthy of the gods!"
And v0, without complaint, obeyed.

Pure vibe coding at its finest.

Plot twist: damn YouTube API 😤

The original plan was to migrate playlists from Spotify to YouTube Music.
But YouTube's API has an absurdly low daily quota, so I couldn’t perform large-scale searches.

So I had to pivot.

Now, we only support migrating from YouTube to Spotify.
A downgrade in functionality, but an upgrade in reliability.

Saved by AI (thanks Gemini)

One of the biggest challenges was matching songs between platforms.
YouTube doesn’t return track titles exactly as expected, which made finding the same song on Spotify a mess.

So I integrated Gemini, Google’s AI, to help normalize song titles.
With AI in the loop, match accuracy improved a ton — even when titles were weird or full of typos.

Conclusion

PlaySwap was born from a personal need, shaped by modern tools, and enhanced with artificial intelligence.
It’s not perfect, but it’s useful, fast to build, and above all, fun to make.

If you’re thinking about trying this vibe coding approach — let me warn you:
it’s addictive. 😎

PS: If YouTube ever raises its daily quota, the pharaoh promises a new version that migrates playlists in both directions.
And yes, ironically, I ended up building an app that does the exact opposite of what I originally needed.
But hey, at least it looks good! 😂
