So, you are telling me music is haram. Can you tell me where in holy Quran, Hazrat Muhammed (saw) called it haram and prohibited singing? I stress holy Quran is perfect. So, don't quote me Hadits and surah written years after prophet (saw) on this particular matter and use it to convenience while you enjoy these kinds of qawwalis.
And I don't want to brag about nobleness. Because the titles, family lineage or even beauty of qabr doesn't matter to the almighty. That's why Kerala Muslims are humble, tolerant, may be because we've been practicing before anyone in South Asia.
