this is so weird but kinda good lol, it obviously was made to be happy and fast paced, we can hear it with the chords loopings every 4-5 bars is a weird chord (i forgot the name of the type of chords that sound "bad") so because this chord isnt necesarily good sounding, it plays fast during the song, so you hear it but dont pay attention to it because the song is too fast paced. This slowed version sounds like it switches from major to minor, or the opposite, every 4 bars
it also only has 3 chords in 1 bar which is only used to go back quickly to the first chord during a fast song, and because this "technique" isnt used a lot in slow songs, if ever, the chorus sounds off
