ImAiiR/QobuzDownloaderX ? reverse-engineered prompt

Build me a simple Windows desktop app that connects to Qobuz, lets a user sign in, browse their account, search for albums, artists, and tracks, and download the music they’re allowed to access for offline listening. I want it to feel like a practical downloader, with a clean interface, clear progress updates, a queue, and an easy way to pick where files get saved. It should also handle basic errors nicely, like failed logins, unavailable tracks, or bad connections, and show the user what went wrong in plain English.

Use the existing project as the starting point and make sure it runs smoothly from the solution. If you need current implementation details, look up the latest docs or APIs online first. Keep the app focused on music downloads and library management, and make the experience as polished and straightforward as possible.
