@Former-Member - I think for me the fear of thunder is the lack of control, hearing it outside without the fear makes me feel like I am in control and can turn off the thunder whenever I have had enough of it.
I find spotify in my car is able to find the exact song to play, although its scanning my previous song requests it always manages to find the song that suits my mood and even manages to brighten it.
I wonder if you would like to play "quote the first song in your head".
For me just then it was Michael Jackson - Thriller. I have always wanted to learn the dance so I can join in parties but unfortunately my skills of dancing may leave much to be desired hehe.
My favourite mood upbringing song would likely be the "Conerning Hobbits" scene from Lord of the rings.It reminds me of when I was younger, I built a little home theatre in my bedroom (just a cheap projector and some white paint on the walls haha). I did the paint while my parents were away so it was a big surprise that I did it hehe. I put some cheap speakers around the room, and then tried to find a spot for the bed. Would you believe I would lift the single bed and base up against the wall each time I wanted to watch a movie. It was one of my most memorable experiences and has this amazing ability to hold true to this day.
This song makes me feel like a Or The Lord of the Rings - May It Be by Enya. This song has always made me feel like things will be ok even if they are not that great at the moment.
