short technical information for developers
LyricsDB plugin is only available for foobar2k (yet) player. It is just not fair. If you want to make similar plugin for any other player - welcome.
Warning, major protocol change:
LyricsDB is supporting xml-based lyrics exchange protocol (LEP) now. LEP is designed for exchanging lyrics between different applications and servers over the network, and foobar2000 is able to support it by the aid of LyricsDB (since version 0.0.5). Check the description of the LEP, foo_lyricsfb.dll and the database part (lepserver.cgi) just support it.
