YOUR RADIO CHART PREVIEW

We've consulted our Ouija board and now unveil for you the future ... or at least a glimpse of next week's action at three key Mediabase radio formats. Take a look-see, buddy.

TOP 40
A couple of things remain the same this week, keeping the Columbia folks "Happy!" Pharrell Williams remains in the top　slot for one more week, and once again John　Legend's "All of Me" is this weeks Greatest Gainer. Joining the Top 10 this week is RCA's Justin Timberlake with "Not A Bad　Thing," while Columbia’s MKTO　moves to the Top 20 with "Classic." Strong growth this week has Austin Mahone f/Pitbull’s "Mmm Yeah" (Republic) and Pitbull f/GRL’s "Wild, Wild Love" (Mr 305/RCA) poised to join the Top 20. Capitol's 5 Seconds of Summer is setting spring on fire with a very fast-paced chart climb. "She Ain't You" by 614/Black Magnetic/Epic's New Hollow is bubbling just under and looking to chart this week, as is Warner Bros.’ Nico &Vinz with "Am I Wrong."

RHYTHM
It looks like Pharrell Williams’"Happy" will jump back into the #1 position again this week, with a dogfight coming up between Columbia label-mate John Legend with "All of Me" and RCA's Chris Brown with "Loyal" for the following week. Beyoncé's "Partition," also through Columbia, climbs into the Top 10 this week, and Def Jam has great results with Jhene Aiko’s "The Worst" and Iggy Azalea’s "Fancy." Young Money f/Drake’s "Trophies" (Republic) will also see a very sizable gain. RCA's Justin Timberlake leaps into the Top 25, and his label-mate Tinashe will debut with her "2 On" featuring ScHoolboy Q. Republic’s Adrian Marcel will do the same with "2 AM."

ALTERNATIVE
Epic's KONGOS will stay at #1 for a second week their breakout smash, "Come with Me Now." The Top 5 is full of #1 contenders as the battle heats up with Bastille’s "Bad Blood" (Virgin), Fitz & The Tantrums’ "The Walker," Phantogram’s "Fall in Love" (Barsuk/Republic) and The Black Keys’ new hit, "Fever" (Nonesuch/Warner Bros.).　Next week we’ll also see new movement in the Top 10 as Island’s Neon Trees, Parlophone's Coldplay, Cantora’s Bear Hands and RCA’s Bleachers are all viable contenders.　On the debut side of things, Capitol’s Beck will enter the chart with "Blue Moon."
