HANSON, SHOUT IT OUT (June 8)
In the years since ''MMMBop,'' the brotherly trio has become an accomplished pop-rock group. This is their first album since 2007 — and since lead singer Taylor Hanson made new fans by teaming with members of the Smashing Pumpkins, Cheap Trick, and Fountains of Wayne for the supergroup Tinted Windows last year.

DRAKE, THANK ME LATER (June 15)
The onetime Degrassi: The Next Generation star is already rap's hottest up-and-comer on the strength of hits like ''Best I Ever Had'' and ''Forever.'' Expectations for his official debut couldn't be any higher right now.

3OH!3, STREETS OF GOLD (June 29)
This Colorado electro-rap duo has only gotten bigger since their 2008 single ''Don't Trust Me'' made it to the top 10 of Billboard's Hot 100. For their follow-up, they worked with hitmakers like Dr. Luke, Benny Blanco, and Greg Kurstin.

M.I.A., TITLE TBA (June 29)
The ''Paper Planes'' provocateur made headlines with a recent interview in which she trashed Lady Gaga as a rip-off artist. Now M.I.A. has a chance to back up that bravado with her third album.

N.E.R.D., TITLE TBA (June)
The Neptunes don't feel quite as omnipresent as they did last decade, but the duo (a.k.a. superproducers Pharrell Williams and Chad Hugo) is still staying busy in the studio. Case in point: the upcoming fourth album from N.E.R.D., their band with old pal Shay Haley.

GAME, THE R.E.D. ALBUM (June 15)
Any album released by the West Coast rapper — now going by just Game, no ''The'' — can always be relied upon for banging beats, gravelly rhymes, and more shout-outs to colleagues past and present than you can easily count. His fourth effort should provide all those pleasures, plus a Justin Timberlake collab.

T.I., TITLE TBA (Aug. 24)
Atlanta's sharpest lyricist is back home again after a weapons conviction put him behind bars. The rap scene just hasn't felt complete without him.

MARK RONSON, RECORD COLLECTION (summer)
Details are scarce about the British producer's follow-up to 2007's all-star covers set Version, but we liked that one so much that we're dying to hear what he'll do next.

KATY PERRY, TITLE TBA (late summer)
One of the Boys made her a megastar in 2008. Will her next disc yield anything as huge as ''I Kissed a Girl'' or ''Hot N Cold''?

ARCADE FIRE, TITLE TBA
The Montreal band became one of indie rock's biggest crossover acts with 2004's Funeral and 2007's Neon Bible. Little is known about its rumored follow-up, which may or may not arrive before summer turns to fall, but it's bound to be a big deal whenever it's here.
