Will there be songs in the movies?

Will the characters break into song onscreen as they do in the pages? To some audience members, it may seem corny. Plus, the actors aren't being picked for their musical talents, so they might not be very good at singing. I think it might be best if they cut most of the songs, to move things along a bit and also so that the general audience doesn't get distracted. I think the Elves should sing their songs, but I don't think the hobbits need to sing.
