Hello Hakko, i am using 7.1.9 and i have started looking into batching my lyrics. I use mediamonkey with a plugin called Lyricator v1.1.1 #31 (2010-12-16) which works great to update the lyrics. I tested it on one one album and within mediamonkey the tags are written with the lyrics.
However, when i play the song in MC and click on the lyrics button i get a message in the pop up window "Upgrade to Lyrics Plugin version 0.4"... can u help ? greetings from snowed in Leipzig..
