Definitely 10/10
I've waited way too long with this review. The thing is that I want to find the right words to describe the song. But I've made little progress with that.
Anyway, I think it is excellent from start to end. The melody is very catchy, I haven't forgotten it since I first heard it and I still come back and listen to the song every now and then.
There is one part that always catches my attention around 02:30. It sounds like some kind of filter+panning automation. It sound a bit different on different speakers, so I have multiple opinions about it. On my regular headphones for example, it sounded pretty uncomfortable before I got used to it.
But right now I'm using in-ear earphones and I get a feeling as if something is put over my ears at that part, kinda like a very mild airplane ear. Considering that it lasts only about 10 seconds, that's an amazing effect that I haven't heard in any other song. It somehow makes me imagine taking off and soaring above the clouds.
