Ending Ariana Grande's reign is The 1975, with their second chart topper, Robbers, after Girls went to #1 on the last week of 2013. Also, we've got two huge debuts in the top 5. The first belonging to Lana Del Rey. Shades of Cool is her second #2 debuting song off Ultraviolence, and is her 8th top ten hit. Secondly, we've got newcomer Ella Henderson, who debuts at #4 with Ghost.
Other than that, Lorde snatches her third top 10 with Tennis Court. Summer and Come With Me Now exit the chart after logging a good number of weeks (12 and above is considering as great).
