I enjoy the vibe of this song.
According to the musician, Raingurl is about the moments of introspection you feel when in a large venue like a club. The sudden instances of clarity when surrounded by bass that makes it too hard to talk too much, so you get thinking as you groove.
Personally my first impression was that this incredibly chill young woman was attending a strip club in feminine solidarity and encouraging the dancers to ‘make it rain’, but after watching the music video I can see how the intended tone is completely different to the one I envisioned whilst listening to the car radio.
Ah well. Whatever suits you.
