https://vocalremover.org/pitch you can change the tempo here, and also the pitch
Also the actual song is way faster than the recreation i made but stupid Band Lab wouldn't let me change the tempo.
I made the recreation it's not that great but it's better than a hum. https://voca.ro/16LYuLSSEvwh
i have no idea, likely a synth and some type of bass. I will try to make a recreation in band lab.
Anything on what instruments were used? Guitar, piano, synth?
