I was reading the charts for most viewed youtube songs for the years 2017/2018 . In it, 7 out of the 10 most viewed youtube music videos are in spanish.
Notice this wasnt like this before, in years prior to 2013 there were none and from there on it kept increasing slowly.
Also, I was taking a look at the list of most viewed youtube videos today. In it, of the top 100 songs, 38 are in spanish . I've been seen this chart getting more and more spanish speaking songs regularly. Most viewed youtube videos in the past 24 hours
Is there any known reason why this is happening?
