Several days after they released their own return single, Mobb Deep makes an appearance on M.O.P.'s new single, "Street Certified." The song is as gritty as one would expect from two of NYC's legendary hip-hop duos. While Mobb Deep's self-titled album is dropping in March, M.O.P. has not released any information on their next project.
