Hey Gavin,
Most of the time your songs make me, when I haven't yet played the game they're about, want to be part of it, and when I have, listening to them brings me right back in their respective moods, as people here have said before, you really manage to capture their essence.
Same with this one, the callback to Little Sister is great, just fantastic, and lifts the whole song up even more because you tie the memories of that song and game right into this one.
The many, many positive responses about it here just hammer home how well you pulled the whole thing off (Gwen and Lorna were great as well, of course

), I don't think I've read a single negative response in these four pages yet, quite an achievement on a forum by itself.
I hope you never quit.
