Wrong pronounciation of Jeem (ج)
The letter Arabic letter Jeem (ج) is in the most cases wrongly pronounced. In correct Arabic, the letter Jeem is pronounced like the English J ("dj"), not like the French J.
Well, it really depends on the region your living in, in the shar2iyet region, Lebanon, Syria, Palestine, its a softer j, whereas the khalijjeh region is a bit harsher on the j, for example in jeno w noto, its soft j, as I think the band is syrian.
The letter ج has always been a hot topic in Arabic. I know that in lower Egypt and South and West Yemen, they say it like the letter g but in the Levant (Sham) and Gulf (Khaliij), they say it as a j.
