which school(s) are you auditioning for?
the reason J&H is so frowned upon is because a lot of people don't like the composers. personally, i enjoy J&H...but a lot of people don't.
i'm sorry that my comments didn't boost your confidence...but, having done this whole audition thing twice, i know how much preparation goes into it. since you have "someone like you" nailed and it sounds like your voice is suited for it well - i'd stick with it simply because you don't have much time.
maybe your up-tempo could be something to show off your mix. again, i'd suggest something older since J&H is so modern. it's hard to suggest anything because i don't really know your voice and my voice seems like it would be really different than yours, so none of the songs i have in my repertoire would really work.
honestly, i want you to do well. and i don't know you...maybe you're really good at putting stuff together really quickly. you're just really going to have to kick things into high gear for the next two weeks.
good luck
