Hey Schavuitje!
What can I say? A really hooky guitar riff with a memorable melody, lovely arrangement, nice dynamics, the odd surprise, good vocal harmonies, highly original. Your song has it all!
And yes, the 'falling downstairs' drums are fabulous.
I know from experience that writing a strong melody over some of those unusual chord changes is not an easy task, but you've nailed it.
This would make an excellent track for a live band - I'd love to hear that.
My only beef with the song is the instrumental section. Maybe a taste thing, but the guitar break is very prog, while the rest of the song is much more melodic. To my ears it kind of interrupts the flow of the song to the extent that the end comes as a bit of a surprise and feels out of context.
But very well done, and thanks for sharing
