Huh, that's interesting. The Jungle Book apparently started production before Aladdin but was put on hold to be finished after Aladdin. I guess it is possible that the track ("Arabic Ne Naw") was composed for Aladdin then repurposed for The Jungle Book, or even composed early on for the The Jungle Book and then remixed/repurposed for Aladdin - only to be scrapped and then used as originally intended for The Jungle Book. EDIT: It seems that a version of this track also appears in the GB release of Aladdin.
It definitely was likely for The Jungle Book first, since Aladdin from the start I can only assume was always intended to have renditions of the movie's music. If it was at CES they probably didn't have that track done in time and used a spare track they had on hand just so people don't end up playing a silent level. Good guess, anyway.
