R&B singer Tank decided to blast the American MusicAwards last night after realizing his friend Tyrese was shutout of the R&B category.

“@Tyrese couldn’t even get a nomination for Soul R&B Album as the #AMAs? That’s crazy and confusing! WHAT IS SOUL R&B? I need answers!..,” Thank wrote.

Tank later clarified that he is a fan of The Weeknd, who walked away for the Soul R&B Award for his album The Beauty Behind the Madness. His fellow nominees included Chris Brown and Trey Songz.

“For the record I LOVE @theweeknd album! He also deserves the right to be categorized correctly! Why is he just considered R&B? #worldmusic.”

Ultimately, Tank believes there should be two R&B categories, one for Pop R&B and another for Soul R&B.
