You can find a list of all soundtracks here. The one you're looking for is likely among them.
Thanks a lot for the help.
But it turns out i could not find the track.. Can you or anyone plz watch the end of the episode - the sozin's comet : the phoenix king and let me know the name of the track... It sounds a bit like agni kai but its not.. Its the scene where zuko and others are talking about June - bounty hunter  as june is fighting a stranger in the bar holding a cup as she fights... Plz
If it's not listed there, I can't help you, I don't think anyone can help you then, cause that list is complete. Sometimes, tracks were used double, so perhaps the track you're looking for is somewhere at the beginning instead of the end of the list where you would expect it.
