Sharing your current [last.fm]{tag/lastfm} track on irc in realtime is very important. :) Here is a ion3 binding that will use xclip to copy the current track info into the X clipboard.

    defbindings("WScreen", {
            kpress("Mod4+grave", "ioncore.exec('echo player/currentlyPlaying | nc localhost 32213 | xclip -i')"),
    })

Put it in ~/.ion3/cfg_user.lua.
