Greetings IjazAhmad.
May I contribute a little reflection on this topic?
I am always wary of what others say or are asking me to say!!!
So let us give a little thought to the phrase " Allahumma salli wa sallam..." What does it really mean?
What are we asking for now?
When the prophet -pboh- was alive, Allah and his angels" Wusalluna alla nabi"" meaning they helped and supported him , so those who believed should have "sallu alaihi" i.e helped and supported him also .
Now that he is no longer with us how can we "salli alaihi"?
To me it does not make sense. Meaningless words uttered without proper understanding. It is like "parroting" phrases.
So the song in question is meaningless, however if one wants to listen to the music because they like the beat, it is a choice.
I suppose the intention behind what we do is very important. There is nothing wrong with clean art,whether music or other.
Having said that ,a lot of music is fine and enjoyable. GODs gift to us.
GOD bless you.
Peace.
