How do I keep my music library clean and scraped? It is a mess, barely no correct album artwork, I cant find any albums when I search for album info, etc etc. General tips on music library management would be very helpful. (Naming conventions, how to scrape properly, etc)
XBMC needs good ID3 tags in your music files, so try something like
MusicBrainz Picard (wiki) to correct them.
Just as Ned said, XBMC will ONLY read the tags of your music, not whatever naming convention you use for filenames. I personally used Mp3Tag to re-do my collection. It may take some time, but once everything is done correctly it really pays off.
MediaMonkey has some nice features also, auto tag from the web, embedded cover art...
