I guess one of the reasons why "La Vuelta al Mundo" has so many views is because of the lyrics. From the perspective of a non-Spanish speaker, the song might sound like simply a guy talking, without any artistic talent. However, what makes this song so interesting is the meaning and how the writer structured the song.
The song basically tells how a man realizes that his life sucks. He has spent his whole life studying to get a good job, and once he has the job and a good salary, he is not happy because he is not doing what he really likes. So after a while, he decides to quit after proposing to his girlfriend. The story is quite simple, but from a literary point of view, the lyrics are very interesting to read as a poem, since they play with the double sense of some words and expressions, and the writer uses this to criticize some aspects of the society he doesn't like.
In fact, they became popular in Spain and Latin America during the early 2010s because of the way they wrote... The music is not the only thing to determine if a song is a good one or not.
Just to be clear, writing this comment does not mean that I entered the song.
