No disrespect but your experience with foobar seems like the inverse of how it works? It definitely has a Library function, but my workflow for using foobar for years now is:

- Install

- Turn off visualization

- Drag and drop folder full of audio on the main window

That's one of the things I like about it the most: I do a ton of reorganization of my audio, so the fact that foobar can run in 'dumb' mode is a godsend.
