Can you help me pick out some songs for the dance themes "Rags to Riches" and "When I grow up..."?

There are these two themes that our dance teacher chose for the dance show which are "When I grow up..." and "Rags to Riches" and our job is to think of songs to go with the themes, to be honest I am quite useless when it comes to categorising songs. We've already got When I grow up by the Pussycat dolls as the opening for the "When I grow up..." theme. I was thinking for the other one "Rags to Riches" that we could start a song a "dreamy" song (I mean like Billionaire by Bruno Mars and Travie McCoy) and then end with Jessie J price tag as to show that there is more to life then having money BLAH, BLAH, BLAH,I am not trying to be picky but I think everyone would prefer songs that are current rather than older, we are also going to be doing hip hop and street-dance styles but I think we are going to do at least one contemporary or of a slower beat, also if you could think of any other themes with some songs, that would be great as well! 10 POINTS TO THE BEST ANSWER!!! Tip: I am looking for lots and lots of songs which are related to the themes and are current!
