Neigh has nothing to do with a horse. She's actually a Danish vocalist, and her contribution to this song by Caius is top-notch.
The two apparently spent a long time trying to come up with the perfect sound, and I think their work paid off -- "Your Love" is simultaneously groovy and easy-to-digest. Every time it comes up I find myself slipping into a happy place, which is a good thing for a song to do.
(Caius is also Danish, in case you were wondering.)
