As I already said in "How did you discover...", at the moment I only know The Great Escape and Mercy Falls.
Mercy Falls: so far One Last Goodbye (I like sad songs; and I like duets, so the additional female lyrics caught me), but recently also Hide and Seek (I just love the Chorus)
The Great Escape: difficult; first I preferred Alley Cat, then King of Whitewater, then The Angelmaker and recently I even got into The Great Escape (previously, I didn't have time to listen to it actively and it just didn't stay in my head).
Maybe it should stay King of Whitewater, I just love violin^^
The Great Escape is a little too long for me (although I think for some, its length might be what it makes the best song). I sometimes wish to listen to a certain part of it but can't, because it's in the middle of the song. I kind of would prefer it hacked into many small songs, but that would take away the anthem-like character, so I'm ok with how it is. (Sounds so negative, but I really like this song!)
