Kaa the shade is SslikGhost04 just like Bloodmage Skulks, so they'll play it, too. But they are pretty tough anyways, so think that should be appropriate.
Lem the cold is SarisGhost05, but many low level mobs use that race too, so he's excluded from playing boss music.
Fafnir is a blighthound, but so are are the regular Blight Hounds. But those are fairly tough, too, so left it to play for those.
Gruk the Frigid is Aegror00 which is shared with some lower level mobs, so his music is excluded.
But all other bosses should have unique race. Think those were the only exceptions.
All the boss mobs in Rift (Guardians & Elial), Blight Anchors, Lesser/Greater epics and rop/arop bosses should play it, but keep in mind the exceptions.
Will look into making Gruk, Fafnir, Daknor, Lem, Kaa a unique race so they only plays the music; prevent the small number of other like mobs from playing it.
