YOUR RADIO CHART PREVIEW

Buddy! We're gonna share our predictions about next week's key Mediabase charts, even though you've probably started your holiday drinking and won't even remember. Ah well, be sure to check out Tuesday’s re-cap after a lengthy nap and a fistful of aspirin.

TOP 40

We have a new #1 this week; RCA’s Justin Timberlake takes the crown with "Not a Bad Thing!” This week's Greatest Gainer and current #4 is “Fancy” by Def Jam's Iggy Azalea. Columbia has two moving in the Top 10 with DJ Snake & Lil Jon’s "Turn Down for What” and Calvin Harris’ “Summer." Republic's Ariana Grande looks to be next up to join the Top 10 for "Problem" f/Iggy Azalea, after another great spin increase week. Other big spin increases include Magic!’s "Rude" (RCA), Sam Smith’s "Stay with Me" (Capitol) and Jason Derulo f/Snoop Dogg’s "Wiggle” (Warner Bros.). Epic's Michael Jackson & Justin Timberlake will reenter the chart with “Love Never Felt So Good,” after a big spin increase week fueled by sales stories and a "sort of" TV appearance.

RHYTHM

It looks as though Columbia will get yet another #1 record, this time with DJ Snake & Lil Jon’s "Turn Down for What." It’ll narrowly hold off Def Jam’s Iggy Azalea and "Fancy." Republic’s Ariana Grande leaps into the Top 10 with "Problem,” as will Def Jam's YG and "Who Do You Love" f/Drake. Big moves this week also include Childish Gambino’s "3005," via Glassnote, Warner Bros.' Jason Derulo f/Snoop Dogg with "Wiggle," Republic's Lil Wayne and "Believe Me" f/Drake, and Pharrell Williams’ "Come Get It Bae,” via Columbia, which will also debut.

ALTERNATIVE

As we enter Memorial Day weekend, historically the currents take a hit, as many stations go into specialty programming. That said, look for The Black Keys to remain #1 with their hit "Fever" (Warner Bros.). Virgin's Bastille is right behind at #2 with "Bad Blood," as that one’s clipping at the Keys’ heels. RCA's Bleachers will enter the Top 5 with "I Wanna Get Better." Jack White's "Lazaretto" (Columbia) arrives in the Top 10. Warner Bros./Crush’s Big Data is having a huge week of spins with "Dangerous.” It’s now knocking on the Top 10's door at #11. Columbia’s Foster the People quickly moves to #15 with "Best Friend." The buzzing Tove Lo makes a nice move to #25 with "Habits" (Island), and Coldplay's new single, "A Sky Full of Stars," will make its chart debut.
