The TV series Westworld had a scene where they had Shogun era musicians playing a Wu Tang Clan song on traditional Japanese instruments. https://www.youtube.com/watch?v=__DEAK3AinM
Yeah, that sounds right. There are some producers that can stand on their own though too, but they would probably do well in the metrics in TFA.
When a piece of music is both simple and captivating, I view that as a huge achievement. I can play simple songs, but no one wants to listen to them (and rightly so!). The Ramones can play even simpler songs, and they are special. I have no idea how to measure something like this.
It's shocking how if you take a song from a genre that is focused heavily on vocals and take out the vocals, it's not a very interesting song anymore. I think rap -> poetry is a more common conversion than rap -> orchestral music because the latter is just crossing too big of a divide between music styles.
The sounds other than vocal part of Dr Dre’s album probably wouldn’t really stand on their own and much is quite repetitive (as noted in the study).
Led Zeppelin Immigrant Song can definitely be enjoyed without the vocals, though the vocals really make it recognizable.
Similarly, there are quite a few rock songs that have been made into pretty interesting orchestra pieces.
Would be interesting to see if there any hip hop masterpieces that have been arranged for classical music.
