I don't think the firmware was written to handle .tangara-db being deleted while the device is running. If you're deleting .tangara-db, yeah, I'd definitely recommend removing the SD card and doing that from a computer with a card reader.

Yes. I’ve been powering down the device, removing the SD card, and using a computer to delete the db file. I did notice that I had some .m4a (aac and alac) files and embedded album art, so I’ll be removing those next and seeing if those help the process.
