Unfortunately, the Media player seems to cache metadata. I had some incorrect metadata on a few of my FLAC files on my jump drive. For instance, some songs had the genre listed as "Hip Hop" and others as "Hip-Hop". Some had "Goo Goo Dolls" and others "The Goo Goo Dolls". Obviously this causes a bunch of extra entries in the media player genre/artist lists, so I brought my jump drive in from the car, plugged it into my computer, and made some changes to the FLAC files using Kid3. Once I'd cleaned everything up, I put the jump drive back into the car, and....nothing changed. It seems as though the Model S caches song metadata. So I said to myself: No problem, I'll just reboot the screen. Didn't fix it. Then I removed the jump drive, rebooted the driver's console and the main touchscreen, then replaced it. Didn't fix it. Then I tried putting in a different jump drive, removing it, then replacing it with the original. Didn't fix it. Then I thought that if I changed the name of the jump drive volume, the car would see it as a different storage device, and not use the cached info. Didn't fix it. Has anyone found a way to "clear the cache", so to speak, so that the drive and all of its metadata is rescanned? I'm on 4.5 (the .44 flavor). I remember that in the past, I'd frequently see the drive getting parsed/scanned, but I haven't seen that lately. Trying to figure out how to get it to rescan so I can refresh the incorrect metadata. This drives me bonkers.
