I own a 2018 S90 this issue with Gracenote irritates me every time I drive the car. Is there any way to completely turn it off? I listen mostly to jazz and I guess since a good amount of the music and artists that I listen to are not very popular, Gracenote replaces their names with something else. It comes up with names like Holly Johnson instead of Henry Johnson, and countless other incorrect names. It makes it difficult for me to find some songs because the artists' names are so messed up. I've meticulously gone through all of my mp3 metadata to make sure everything is correct. I notice that if I place the USB drive in after the car starts and after Gracenote has already loaded, the artists will display properly for a while and then revert to the Gracenote after a while. I've tried changing the volume label on the USB drive, Disabling Gracenote in the Sensus settings, I have the latest Gracenote update, and nothing seems to work. Is there a way to clear the cache in Gracenote and completely shut it off even when I start the car? I just want the data from the USB drive to display, not information from some other database. Is this so difficult?
