I'm pretty sure that I actually could, if I really wanted to, create this cover legitimately and even put it on Spotify with royalties going to the original artists (it seems they have a blanket mechanical license for a lot of works). But it was a "gag" song that probably has a market of just me, so hiring a team of people would be a lot of time and money for 3 minutes of a giggle. I also would have to worry about things like if it's changed too much to be a cover and getting sued for putting in extra effort.
