I live in OR, we get plenty of rain but not much snow xD I'll try listening to it during a snowy day, though. Maybe listening to it at the right place at the right time will shed some light on it. Personally I like listening to Close to You during the winter times. Any other time of year that song does
nothing for me but during winter, on a peaceful white night, it's perfect. When I lived in AZ as a teenager, we got a terrible snowstorm and I was snowed in by myself for two days because my parents were in Phoenix at the time and couldn't get home at the fault of the weather. I was a bit freaked. I was high in the mountains, secluded, lost electricity, wasn't all that stocked up on food, and every time I called the phone company they couldn't give any sort of indication when the power would be back on. So I had nothing else to do but listen to my iPod and watch the snow fall. Close to You came on and for five minutes I wasn't worried. It was really peaceful, actually. Everything just... fit. Falling snow. White mountainside. A still wind. Fire cackling in the hearth. (Still didn't get electricity until afternoon the next day and my butt was frozen to the seat I was on, but whatever.) Even now, near ten years later, when it snows, especially at night, I try to recreate that moment. Turn off the lights, light a fire, turn on Close to You and watch the snow fall.
Sounds cheesy, I know, but that's what's music is for, I suppose, creating memories even just for yourself.
... I just realized this had nothing to do with what we all were talking about but this just came to mind so I'd thought I'd share. Sorry for the blubbering. Listening to and/or talking about Ayu's old music gets me reminiscent I suppose! xD
