The joy of El-P and Killer Mike's Run the Jewels pairing is infectious. For their sophomore effort as a duo, they're allowing fans to pay whatever they want, if they want, and are also offering an obscene number of different packages for diehards to choose how they want to demonstrate their fandom. They've just dropped "Oh My Darling Don't Cry," as part of the Adult Swim singles series, and it shows the two veteran MCs are still in top form. Their chemistry, trading verses and picking up on each other's punchlines, along with the all-over-the-place production, makes the song sound like a classic '80s hip-hop with production from 2036.
