Does Rihanna gotta fight for her right to party? is the question Soren Baker and I take on in this episode of The Aftermath, the best music discussion on the net. After Chris Brown and Drake were rumored to be taking jabs at Rihanna on their respective songs, "Theraflu (Freestyle)" and "No Lie," the godfather of rap Russell Simmons chimed in. Simmons suggested that people stop complaining about Rihanna's decision to sow her wild oats because guys are celebrated for doing the same thing. The Aftermath helps decipher the nonsense.

The lively, feel-good song premiered on Ryan Seacrest's radio show Monday. The R. Kelly production highlights reasons to be happy.

Whitney Houston and Jordin Sparks' "Celebrate"

Houston sings, 'I'm going to give you a reason why you should clap your hands and jump for joy."

Sparks, who paid tribute to Houston at the Billboard Music Awards Sunday, sings, "The sun has chased all the rain away. No more obstacles in our way."

Big Sean at Detroit's Lincoln High SchoolBig Sean spent Monday serving as principal for the day at Warren, Michigan's Lincoln High School, winners of the Get Schooled's Detroit Attendance Challenge. Lincoln High competed against 16 other area schools and took first place by improving its attendance record by 8.56 percent year-over-year during the competition.

Big Sean was joined by other celebrity Michigan natives. Royce da 5'9 performed and Mike Posner made an appearance. The "Dance (A$$)" rapper told Hip Hop Media Training that the experience reminded him of his days attending the city's Waldorf School and Cass Technical High School, where he graduated with a 3.7 GPA.
