Finally some movement at the top of the chart this week! Congratulations to Jason Derulo as "Want To Want Me" (Warner Bros.) claims its destiny as the #1 pop song 14 weeks after impact. It may be short-lived however, as Big Machine/Republic juggernaut Taylor Swift glides inside the Top 5 with "Bad Blood" and is the chart's Greatest Gainer again this week. Meanwhile the girl-power anthem "Worth It" from Syco/Epic's Fifth Harmony f/Kid Ink continues to build momentum, ascending to the #8 slot. 222/Interscope gets into the Top 10 with "This Summer's Gonna Hurt" by Maroon 5, and S-Curve/ Hollywood's Andy Grammer locks in at #10 with "Honey, Im Good." Omi's "Cheerleader" lands inside the Top 15 for Ultra/Louder Than Life/Columbia and XO/Republic wonderkid The Weeknd is sitting just outside the Top 20 after less than a week of airplay on "Can't Feel My Face." Adam Lambert's "Ghost Town" (Warner Bros.) and Rachel Platten's "Fight Song" (Columbia) both cruise up into the Top 30. Capitol's Tori Kelly will chart this week with "Should've Been Us."
