chiodos reference shakespeare pretty frequently in their first album. might wanna check this out. -> http://en.wikipedia.org/wiki/All%27s...iodo s_album)
this one's a little subtler, but in the OutKast song 'ATLiens' there's a line that goes "the world's a stage and everybody's gotta play their part," which i'm pretty sure is almost a direct quote from Shakespeare. http://rapgenius.com/Outkast-atliens-lyrics#note-37879
you could prob find loads of Shakespeare parallels in like, modern movies and television btw. since the dude came early and essentially laid the foundation for a lot of western plotlines and story structures, i'm sure there would be say, traces of Romeo And Juliet in 90% of any romance movie out there. Or like, you could draw comparisons between Macbeth and any book or film revolving around corruption or self destruction. but that's just my take on it.
Good luck with the paper =]
