I don´t wanna play producer but I made some notes in my amateur way while I was listening. I hope you don´t mind...

nr 1 like the sound of a turning squeaky tram with the melody in the background
nr 2 too much vocals
nr 3 like the change
nr 4 many sound effects and its quite captivating in the beginning but nagging lyrics
nr 5 best so far... or is it me who´s getting used to your sound
nr 6 really, skip the lyrics
nr 7 too much copy of... I don´t know
nr 1-8 some cool elements but I would really tone down or defuse/distort the vocals in general or have more highlights in the music to take over.
I would put it aside for a while and try to develop it later.
