I know this was from a year ago, but imma comment anyways. I definitly agree with your statement, the original of this song, as well as many other originals are already perfect in and of itself. It's fair to say that when it comes to the originals, we have great memories in connection to these songs. As time flies, whether it's month or years down the road, listening to the original songs slowed down feels almost nostalgic and beautiful in the sense that you're brought back to the "good days". It basically leads to the "slowed down" genre, which nessacarily isn't a genre, but is frequently searched amongst many songs. So, when the title is "slowed to perfection", it's basically refering to perfection in terms of being slowed down to the right tempo.
