Song's titles

Can someone please tell me the name of the music that plays during the video of Shuyin's-Lenne's final moments in Deon Of Woe(this that Shuyin plays on piano)and the one that plays when Yuna recalls her past somehow before fighting Vegnagun?(when she says "I don't like your plan,it sucks!)

1. Nightmare in the Den
2. Yuna's Ballad

Nightmare is the Den is also called Nightmare of a Cave on some sights.

Thanks!^_^
