hello, i'm having problems understanding the line
النغم رجعت حلاوته لقلبى وفضلك قساوته
والهوا اللى بان عليا ابتديت تعرف غلاوته
i think it means "the tune brought back happiness to my heart (but) you prefered it's suffering, and the love that left me started (...)"
I dont understand the last word, but is the rest correct?
