I don't know. This song is nice to listen to, but there's something that the song is missing. It seems to be missing a bit of...Soul....
It's relaxing and enjoyable, well composed and nothing is too loud or quiet.
I really fucking like that click every 2 and 4 beats. The sidechain and chords made me smile. Great work man. But I still feel like there isn't passion put into this song, I just don't hear the "UHMPF" of true hard work. I imagine you worked hard for this, but it sounds to me that there is a perceivable passion put into people's work that other people can see.
Anyway, I think a 4.5 is well deserved.
