Southern rapper Post Malone has returned with yet another slow drugged out feel good track. 'What's Up' features artist 1st Drop who adds a dope verse onto Post's track. Together the two mix very well while FKi & Charli Handsome produced the record. Each producer did an amazing job, the slow auto-tune and doubles sound extremely well. Post has released a few dope tracks including his recent release 'Too Young' which kinda has the same feel. Give 'What's Up' a listen and see if it's your vibe.
