Glad you listened! The cover was a big inspiration for me and I had it open in a window next to my DAW the whole time composing. I'm also a pianist so I opened my piano patch first to sketch ideas and couldn't help but keep the intro solo piano because I liked it too much.
I don't mind answering your question even though it makes me feel old heh. I wrote little songs on the piano when I was a kid, so something like 15 years. 10 years with an actual DAW, and then I bought my first midi keyboard like 3 years ago when I finally finished school and got free time back. Long answer, but I think those are pretty important milestones in the whole creative process.
