RobVel There's a bit of a "Viva La Vida" feel to it. Both songs sound kinda cheerful, but then you look deeper into it and realize what it's about.
Aouwwww. That song is cute. It feels like a warm hug after a lot of suffering. Actually, yes... "Viva la vida" makes me feel like if I were in a movie seeing everything that I have done in the past, the good and the bad. It has this insightful feeling!
I would like to recommend you a song called "Il est ou" by SAAM. I think it talks about being happy, but the whole atmosphere feels kinda sad... And the outro feels rageful.
This song can go with the others in a playlist of "bittersweet feelings".
