Doctor and Derpy? That is totally my OTP when it comes to whooves. Twilight was fun and all, but Derpy is perfect. Get that in the first slot, and a creepy jazzy/instrumental piece dedicated to the Everyfree Forest in the second slot.
1.) Heceta - FritzyBeat (Vocal)
2.) Jastrian - Into the Forest (Instrumental - Jazzy)
