[PROBLEM] Clearing cache

[channelhugger]

Thanks again. Now resolved. Just received another copy of the album & ripped that to flac and updated the library and all looks & plays fine on one of the Raspberry Pi's (actually a USBridge Signature). Rescanned the library on the other Raspberry Pi and the album shows with incorrect cover art & one of the tracks shows as tagged differently than it actually is. I've written a backup copy of Moodeaudio to a micro SD card & rebooted the Raspberry Pi & everything is perfect. I've reripped the original album again and tagged exactly the same and the errors reappear despite no errors and perfect playback. So it looks like a combination of a dodgy disc & a corrupt copy of Moodeaudio.
I appreciate the assistance greatly. Now need to relax and listen to some music.
