I’ve just written a Perl module to fetch lyrics from www.lyricwiki.org and released it to CPAN.
It’s a fetcher designed to be used with Lyrics::Fetcher module on CPAN">Lyrics::Fetcher (although you can also use it directly without Lyrics::Fetcher).
Get Lyrics::Fetcher::LyricWiki module on CPAN">Lyrics::Fetcher::LyricWiki on CPAN now (it’s just been released and will take a little while to reach all the mirrors so if it’s not there when you read this, give it a little while :) )
