I think my favorite Laruku songs are Be Destined, Shutting from the Sky, Vivid Colors, and And She Said. I love old Laruku the best, although all of their new stuff is amazing too. In my opinion they're one of the few bands that doesn't get horrible with time. They've been amazing since their first CD.
Oh! And Kaze ni Kienaide! How could I have left that one out? Silly me.
