In reply to eric.

He rarely does more than 1 song with any artist. He already did 2 songs with Monica. Plus, a collab with her won't help him at all. If it was Brandy who asked him, he'd say yes cuz she has a higher profile in the industry. Like if Beyonce asked him to duet, he'd do it cuz of her status too. He has a diamond album and outsold all his peers not named Mariah Carey. He deserves to be picky with his collabs lol
