Currently totally obsessed with "Monody" by TheFatRat: The song sets the mood for adventure, and the flute parts (especially the ones that come in at 1: 30 and 1:48) just scream "Abigail" to me. There's also some singing at 2:48, which unfortunately doesn't really sound like how I'd imagine her to sound :/ oh well.
Ohh, I absolutely adore that song Had it on repeat for days when I first found it earlier this year and still play it when I'm in the mood for upbeat music. (Which I am frequently) Never made the connection to Abby though, but I can see what you mean.
