I can only copy one song at a time from an iTunes playlist

I'm using Windows 11 Pro. I'm trying to copy playlist contents onto a USB, but iTunes will only let me drag and drop one file at a time. I can do more from the library, but the songs aren't organized, so I want to do it from the playlists. Dragging and dropping doesn't work, neither does cutting and pasting. There is no error message. Instead, nothing happens. To be clear, I've done this in the past with no problems. Any help would be appreciated!
