The lyrics.wikia.com algorithm malfunctions with artists with cyrillic names. For this track the lyrics can't be downloaded:

artist: Эпидемия
album: Дорога Домой
track: Феникс

The link is: http://lyrics.wikia.com/%D0%AD%D0%BF...B8%D0%BA%D1%81

It might be difficult to create an algorithm to handle this [1] doesn't have the latin alphabet part, [2] is case insensitive. And this is just a quick search. Although http://lyrics.wikia.com/Эпидемия redirects to the part with latin alphabet, the subpages don't. Maybe it'd be a good idea to allow users to override tags just for the lyrics download? It's quite serious, because OMP lyrics download is useless when it comes to Russian-named artists.

PS. I did report this to Lyrics Wiki, but overriding metadata would be a very useful request, e.g. for titles like "$SONG_TITLE (Live)"
