Mmm... those last two were my favs from that list. 
You Smiled Kindly- Tomoyo Mitani 
Totally follows my trend of sad, emotional songs. Had no idea until now it was a dot.hack series track. 
 
Ame Agari- Moeko Matsushita 
for some reason, I always tend to listen to it either before or after the above song. 
 
Tasogare- Do As Infinity 
One of my top favorites of all times, I love the emotion she puts into this song. Can't find a legit full length version of this song, but that's probably cuz you can buy it from itunes. 
 
Eternal Love 
From FFXIII, I never would have heard this song if it wasn't for Ikaru. Thank you, Ika.
