There’s this genre of music in Brasil called funk (don’t confuse it with american “Kung-fu fighter” funk, is way different). And people do “mixes” where they slow down and add reverm to the songs, but now the own funk djs are releasing song that are slowed and revermed from the lets go, without releasing the original song. Idk what’s the idea behind that, im supposed to look for a speed-up non reverm mix now. Also, those slow down reverm version suck big time, except when are done by actual Djs in parties, there are pretty cool cause you can feel the bass making vibrations on your chest.
