I don’t think Spotify was ever a Qt application. Back in the day, it used a custom cross platform UI framework they called Spider. But it was XML based, similar to QML.

The early versions definitely used Qt on Linux

Would you happen to recall where you found that?

not the person you asked, but the spotify deb repository used to contain a spotify-qt package that later became a transitional package to the current package

I assume you’re referring to the desktop app? I’m more interested in what’s running on Car Thing.

Is there anything suggesting the old desktop app and the Car Thing app share technology?

It started as a win32 application without any UI toolkit other than the controls that are built into windows. That's how the binary could be only a few hundred kilobytes in size.
