If you thought YouTube's music video charts would be a logical fit for YouTube Music, you guessed correctly. The streaming media giant is rolling YouTube Charts into its Music service as playlists that you can find either on the app's home screen or through a search. If you want to listen to the most popular or trendiest songs, they should be a short hop away. All 29 YouTube countries will have both global and local versions of the top 100 songs and top 100 videos, and you'll also find a local-only top 20 trending list.
