Speaking of single’s of off Eminem’s REVIVAL, Eminem.com recently updated the “Walk on Water” listing and it’s being refereed to as the “first single” off the album. It’s very possible that the track is not the “lead single” similar to what they did with Survival back when MMLP2 released and another track can be named the “lead single” instead.
