It's tradition man, they've been doing it since Snow White in the 30's. They keep/grabs the child's attention, sometimes help move the plot along(like in Hercules), and they just make the film more memorable imo. For me, the songs are usually the first thing that comes to mind when reflecting on a Disney film. Can't imagine The Lion King without "Hakuna Matata", Aladdin without "Prince Ali" Beauty and the Beast without the title track.
