NotiLyric is a python lyric library. It's very easy for applications to use.
NotiLyric can download lyrics from the internet (QQMusic is the only providor now) and display current line using a bubble notification.
Based on NotiLyric, I offer you the following lyric display programs and plugins.
Display lyric for FMD.
python2 fmlyric.py [options]
Options: -a for FMD address (default localhost), -p for FMD port (defalt 10098).
Display lyric for MPD.
python2 mplyric.py [options]
Options: -a for MPD address (default localhost), -p for MPD port (defalt 6600).
QLyric is a lyric plugin for QuodLibet.
First copy necessary files to QuodLibet plugin directory.
cp qlyric.py notilyric.py ~/.quodlibet/plugins/events/
Start QuodLibet and enable QLyric plugin. You will see a bubble notification on screen displaying lyrics.
python2 and python-notify are required, python-mpd is a must for MPLyric.
