Music?

This morning, when I sat down for my morning websurf, my computer was... unresponsive. Moving the mouse woke up the monitors, but clicking yielded no results. I finally went for a manual reboot. When it came back up, mouse and keyboard were fine, but I found that Windows Media Player couldn't find most of my music. (It displayed the first twenty-four, alphabetically by artist.) I verified that the music was still there, and I could play it by clicking on individual songs, but... this was unsatisfactory. I've shifted over to Groove, which recognizes all of my music, but I have been reminded of the reasons I prefer WMP.

Anyone know of a fix?
