Welcome to Buzzworthy's "The Week In Pop," where we round up new album releases, talk show musical guests and TV performances by your favorite pop stars and more (so you don't have to.)
This week, Marina And The Diamonds challenges social mores via electropop on her new record, and she inspired our own Sam Lansky to write that she's "pretty much the coolest pop star ever." AGREED! She'll be on "Jimmy Kimmel Live" Monday night. Meanwhile, Aesop Rock drops his first solo album in five years, and Serj Tankian releases his third solo studio effort on Tuesday. Both of them self-produced their albums; Serj hits "Jimmy Kimmel Live" on Wednesday. Also, Duran Duran are releasing a live album, and JJAMZ's debut album streets. MTV PUSH Artist Of The Week Azealia Banks and 50 Cent both release delayed and much-anticipated mixtapes. Lastly, Nicki Minaj ushers in the weekend when she hits "Tonight Show With Jay Leno" on Friday.

Also peep the Dr. Luke, Diplo and Cirkut produced "Primadonna" and "Sex Yeah," which is a smart meditation on historical gender inequality: "If women were religiously recognized sexually/ We wouldn't have to feel the need to show our ass-ets to feel free." Sing it, sista!
+ 50 Cent, 5 (Murder By Numbers): 50 just dropped his new mixtape on Friday, and it won't cost you a cent, 50 or otherwise.

+ Azealia Banks, Fantasea Mixtape: Last month, she quit Twitter and on Tumblr said she wanted out of "the rap game", but just prior revealed there'd be a Styles P feature and talked to MTV News about the mixtape saying, "It's gonna be hip-hop, there's a lot of hip-hop on it." The single "Aquababe" is def in the rap vein, too. Confused if it's rap or not? Find out when the delayed mixtape hits Wednesday.
