Buddy! Ready for the weekend? Us too. But it ain’t 4:20 yet; before you unwind, take a peek into the future with our predictions for the future of three key Mediabase formats.

TOP 40
RCA's Mark Ronson takes the huge jump from #5 to #1 this week with "Uptown Funk" f/Bruno Mars just as the song prepares to move to power for several key outlets. Expect him to remain here for a minute! Columbia's Hozier makes the Top 5 move with "Take Me to Church," while Epic's Meghan Trainor enjoys another 1000+ spin week inside the Top 10 with "Lips Are Movin." Over at Republic, Natalie La Rose f/Jeremih’s "Somebody," Nick Jonas’ "Chains" (Island) and Tove Lo’s "Talking Body" (Island) all chart this week, and so does Priory’s "Weekend" (Warner Bros.).

RHYTHM
RCA's Usher will hold the #1 spot again this week with "I Don't Mind" f/Juicy J. Meanwhile, labelmate Mark Ronson f/Bruno Mars’ "Uptown Funk" and Ne-Yo’s "She Knows" (Motown) make a big push towards the top. As for Republic, Nicki Minaj f/Drake, Lil Wayne & Chris Brown’s "Only" (YMCMB) and Nick Jonas’ "Jealous" (Island) are also poised to have 300+ gains. Nicki Minaj f/Drake & Lil Wayne’s "Truffle Butter" and Natalie La Rose f/Jeremih’s "Somebody" will be 400+ spins, as will RCA's Chris Brown & Tyga’s "Ayo." Look for Glassnote's Childish Gambino to debut with "Sober" this week.

ALTERNATIVE
In another close battle at presstime, it looks like Cage The Elephant's "Cigarette Daydreams" (RCA) will remain #1 for a second week just edging out Arctic Monkeys’ "R U Mine" (Domino). It’s possible, moving forward, that Imagine Dragons’ "I Bet My Life" (KidInAKorner/Interscope) or Walk The Moon's "Shut Up and Dance" (RCA), now #4, could make a real run at the top spot. Nonesuch/Warner Bros.’ “Black Keys” continue to cruise up the charts with "Weight of Love," which will make a strong #27-20 move. RCA's Smallpools will debut on the chart with their new single, "Karaoke," as will Harvest’s Matt and Kim with "Get It."
