i'm really like one of the student idea in here about cultural exchange, so i'm add this song by Jamie Cullum ft Carlos Sadness, Frank T & Nita. They work together to make this great song (i know this because it's not like the other Jamie Cullum music style) just like all the people in here work together to make our cities great. my favorite verse in this is "Solo somos uno, somos ciudadanos de un lugar llamado mundo" mean "Only we are one, we are citizens of a place called world":
