Guild Wars 2

Can someone tell me the name of this songs please?

1- On “Capture Arah event” where there is a priest with Eternity at the end , and when we must defend it again ,its not from original battle songs that plays when you aggro more than 3 enemies , only plays there.

2- The song that plays when we must defend the Temple of Melandru , just after killing the priest of Melandru and where appears the Champion Spider (like 4 times or more)

Both of this songs only appear on those events , i ll really happy if someone tell me the name of the songs.

I already checked the original soundtrack of the game (the 3 discs in youtube) and isnt there
