Slowing down a song on a pc can have a robotic sound, so you’ll need a program with optional time-stretching. Without it the pitch will reduce and the bass will be stronger. Audacity can change playback speed, as can VLC even on mobile. Just go into advanced and disable time stretching.
List some music you’ve played slow.
Redbone, great slowed down and sped up from memes
There was a rock/metal song that was also trippy but the title is escaping me
When I think of redbone, I think of the love song, is that the same group? “Come and get your love”
Different. Childish gambino, Donald Glover, the guy from community, also from this meme
In hip hop slowing down music is a common remix, chopped n screwed.
