From what I can tell, it still works, just not all the time. Sometimes you
get the song's message (I forget what it is), but the effect doesn't go away
(DoT, Root, buffs, etc). You may have to use it repeatedly kind of in the
same vein as Pixie Strike, unfortunately. Normally, I will only use it in
standard practice if there is no one dispelling creatures that have nasty
dmg shield. Ever fight those elementals guarding the Reckless Efreet in Sol
A? OMG what a nightmare if they are shielded and you can't remove it - even
at lvl 50. Also sometimes have it memmed if fighting Lava Duct Crawlers.
Thought about using it in case a party member might gets charmed by an NPC,
but never got a chance to try it.
