Ummm, I would never drop a name (Jay-Z) in a song (Party in the U.S.A.) if I had not heard any music by that artist before, but thats just Miley Cyrus. She says she didn’t write the song…so…you still sang it. I don’t think it would have been that hard to actually listen to a song…he has like 4 songs out right now and at least 20 songs in the past. She seems a little bit full of herself…or shall I say annoying! I’m sure she is mostly surrounded by music like hers but still don’t most artists listen to other kinds of music (other than their own kind)…all I can say is …WHATEVER!!!
