Arab Region
YouTube consolidated all data from Middle East and North Africa. All songs in the Global Top 25 are nowhere in this year's list of most trending music videos in the Arab region. Instead, the top honor goes to "Asaad Wahda" by Lebanese singer Elissa.

Argentina
"Gentleman" settled for number 2 in Argentina's YouTube Trending list, while "Wrecking Ball" and "We Can't Stop" reached the fourth and eighth spots, respectively. The top spot goes to the reggaeton ditty "El Amante" by Daddy Yankee (featuring J Alvarez). I mean, how can PSY outview a video with THAT thumbnail?
