You're not talking about the Hall of Fame era Steve Arrington are you?? He was solo but like Prince and The Revolution.
Because these joints were not flops
My personal FAV
The funniest thing his biggest hit chart wise was when he was just Steve Arrington.
I didn't know that song was his biggest hit of his solo career at #8 on the R&B charts. The song is azz cheeks. Gone are the famous deep bassline grooves for that mid 80s beige Adult Contemporary R&B sound
But to your main point, SA didn't have the strongest voice but he had a distinctive voice. Slave and Hall of Fame were better because of it in my humble opinion.
