Brandy LOVES music. She has said SEVERAL times that music is the best way she can express herself. Music is her 1st love. But the music industry is a business. It's one thing to love your profession. It's another thing to NOT like the strings that come along with it.
Brandy never struck me as a very business-savvy person, and this legal dispute only enhances that point. Through the latter part of her career, she has been a victim of not so great business decisions and handing. Knowing this, I can understand why she would be so frustrated or lose passion for music.
She's never had such difficulty or messy dealings in the acting world compared to this as far as I know, and she's said that she prefers that industry more. I don't take her sentiments as not wanting to make music anymore, but making the best out of her situation.
