Apple Music has added a Top Charts section to its Browse tab. In it, you’ll find charts by country, and one for the entire world. These charts show the 100 most popular songs.
The charts are global; Apple hasn’t broken out charts by genre, so what you’ll see in the charts is pop and hip-hop. As such, nearly all the 100 tracks in the US top chart are “explicit” versions of songs. Though if you go to iTunes > Preferences > Parental Controls, and check Restrict music with explicit content, these charts will show the “clean” versions of the songs. And if there is none, then the songs that are only available in “explicit” versions will be dimmed and unavailable for listening, but will still display in the charts.
In addition to the country charts, there are sections with the top songs, playlists, and albums for the entire world (at least those countries where Apple Music is present). You can check these, or your country chart, to see what you should be listening to.
Because that’s really the point of these charts; they show you the music do you need to hear to avoid FOMO, and reinforce the primacy of the music at the top of the charts by excluding the rest.
