Man, there are certain songs that just make me stop what I'm doing and just listen. "Rain" by SWV is one of those songs. Not only is the track soothing, but the voices of SWV are a perfect blend over the melody, and the way they harmonize is just crazy.
I could listen to this song over and over and not get sick of hearing it. That's a rarity. There are only a handful of songs that I can say that about.
