How to run?

1. download the source from kde-apps.org and unpack the tarball, or get the source from version control system (the svn on my blog or launchpad).
2. turn on the supported audio player, like Amarok2, qmmp or audacious etc
3. open you favoriate console (konsole etc), navigating into "lrcShow-X" as the current directory
4. type "./lrcShow-X" in console

It's green package, you could put all the source into /opt, and write a easy bash script to quick lauch the application. If you like Amarok2, there are two options for you to reallize launching lrcShow-X automatically with Amarok2, the URL of these Amarok2 script are:
