Justin Bieber’s new CD, Believe, dropped Tuesday and critical consensus is that it doesn’t stink. The word is still out on “Girlfriend,” Bieber’s second perfume, which also was launched this week and may or may not contain the singer’s sweat.

Of course, the musical sophisticates among us with more mature tastes know that if you are going to commingle bodily fluids and music and be taken seriously, you’ve got to use blood. Critically acclaimed band The Flaming Lips recently released an LP containing actual blood samples of the band and its collaborators.

Blood Sweat & Tears could not be reached for comment.
