Hey Champ, the Lupe Fiasco-approved electro-rock savants, are releasing their first re-mixtape on imeem. On "Winner's Circle," the trio deliver their own genre-bending take on some of the year's hottest tracks, including Passion Pit's "Little Secrets, The Sounds' "Beatbox", Mike Posner's "Cooler than Me", and The Cool Kids' "Champions." With a bona-fide blog smash and a bag full of bangers on the way, 2010 is shaping up to be the year of the Champ.

When two of the planet's hottest performers come together on one song, it's always a big deal -- and "Give it To Me" is no exception. The new video collaboration between Shakira and Lil' Wayne is the second single from Shakira's forthcoming "She Wolf" album. Will it overtake "Hips Don't Lie" as the song you'll sing from sun-up to sunrise?

After beating out fellow American Idol contestant Adam Lambert for this year's AI crown, Kris Allen's life is starting to get pretty busy. These days he's either in the studio, onstage, or on the road. To help break up the boredom of those long city-to-city trips, Kris does what any music-lover would do: he listens to music. Here's a playlist of the songs that Kris jams out to while on tour, including songs from The Fray, Coldplay, Adele, Jamie Cullum, Kings of Leon, Mutemath and Gavin Degraw.

What do Janet Jackson, Lady Gaga, 50 Cent, Rakim, Justin Bieber and Fall Out Boy have in common? They all have new albums out today that you can hear in their entirety on imeem's New Music Tuesday community, brought you by U.S. Air Force.

In honor of Fall Out Boy's 'Greatest Hits' compilation, which arrives in stores today, the Fall Out guys have put together a playlist of their all-time favorite songs from other artists' greatest hits albums.

Fresh off a nationwide tour with his boss and mentor, Jay-Z, J. Cole is heading back home to his Fayetteville, North Carolina home to work on his debut album. Cole's stellar work on mixtapes like "The Warm Up" has attracted some high-profile attention, including that of Notorious B.I.G.'s former manager, Mark Pitts, who first played Cole's "Lights Please" for Jay. Listen to the song that caught Jigga's ear --and the entirety of J. Cole's latest mixtape-- as you watch another star ascend into the sky.

This week's playlist of the 25 most wanted songs on imeem is a great mix of superstars, up & comers, comeback kids and soon to be staples. The demand for Lil' Wayne, his "No Ceilings" mixtape, and his Young Money compatriots Nicki Minaj and Drake is through the roof. And after landing another number-one album with "This Is It," the king of pop is posthumously back on top, alongside Chris Brown, Keri Hilson, Melanie Fiona and more.

If there's one thing that each of the videos in this week's Hot 10 have in common, it's steam. Rihanna stalks the night like a jungle cat in "Wait Your Turn," Trey Songz turns down the lights and attempts to prove that he "Invented Sex," Britney Spears and a gang of scantily clad dancers do what they do best in "3," and 50 Cent implores you to "Have a Baby By Me." Can you handle the heat?

Rihanna's gritty new video for "Wait Your Turn" sees the singer strutting through the dark streets of New York City with a hard new look. It's a tectonic shift in Rihanna's style, drawing more inspiration from early 90's hardcore hip-hop videos than Ri Ri's glamour queen contemporaries. What do you think of Rihanna's new direction?
