to finish out a set

I'm stuck trying to choose between two songs for the final song in one of my sets for Saturday night.  It's a Lebanese restaurant and I generally like to close out the set with a pop song that people will know - maybe try to get them up to dance with me.  These are both songs that people have requested in the last year so I figure they are good choices but choosing between the two.... is giving me a problem. 

I'm looking at either

Nancy Ajram - Ah W Nos....

or

Amr Diab - Noor El Ein. 


The Amr Diab song is the one I almost always go for = good & reliable ... the Nancy Ajram song is newer for me = fun & cute.
I linked to versions with the english subtitles so you can have an idea of the lyrics translation........

I have ALL the rest of the songs chosen for the three sets and only need one of these to complete that last set. ....

Opinions?
