wtf is album-train?

Album Train is a small add-on panel for foobar2000, a music player for Windows. It plugs into a foobar2000 extension called Columns UI and shows the album art from your music library scrolling across the screen in a horizontal row, similar to a feature once found in a Sony music app called x-appli. Only the 64-bit version of foobar2000 is supported, along with a recent version of Columns UI. You install it by downloading a component file from the project's releases page, then adding it through foobar2000's preferences menu. Once installed, you add the Album Train panel to your player layout using the Columns UI layout editor. From there, clicking an album's artwork once adds all of its tracks to a new playlist, and double clicking does the same but also starts playing the album right away. Right clicking gives access to a settings window and, when clicking directly on an album, a way to view and select that album's tracks. The settings window lets you adjust how the panel looks and behaves, covering things like image quality, scroll direction and speed, whether album names are shown and in what font, and background appearance. There is also a simplified Stability Focused mode that automatically lowers image quality to reduce strain on your computer, and a separate Hardware Acceleration option that only turns on if you have an NVIDIA graphics card, which can make the scrolling motion look smoother. The README includes a detailed frequently asked questions section covering common issues, such as artwork not appearing because it was tagged as something other than a front cover image, or the panel running slowly on lower-powered machines. Support for foobar2000's other interface, called Default UI, is planned but not yet available. The project does not state what license it is released under.
