Every year in Hip-Hop there is a track that penetrates the Zeitgeist and inspires countless MCs to want to leave their imprint on the record. In 2013, it was Big Sean’s “Control,” fueled in large part by response records to Kendrick Lamar’s lyrical assault on the entire industry. In 2014, Bobby Shmurda’s “Hot Ni**a” had legions rapping to Jalil Beats’ thunderclap. This year, two tracks appear to be in the running. Earlier, seemingly everyone wanted to touch Fat Joe and Remy Ma’s red-hot “All The Way Up.” Even Jay-Z blessed the track with one of his most well-received verses in years. Lately, however, the honors belong to Young M.A.’s “Ooouuu.” Over the last 2 weeks, the song became an aural weapon in the ongoing war of words between The Game and Meek Mill, with both men using the beat for diss records. Now, 50 Cent adds his 2 pennies.
