hahahah my youth team wanted to dance to i like big butts...lol i still laughUgh, I can't help, I hope someone answers you! I am in this same situation... My mini team tried to convince me they needed "Sexy and I Know It" in their music last night. This was my face:
I like the Disney idea - I think Disney has been really spinning there own "pop" sings for a while now. I actually will go on Itunes and buy those and do mixes for my daughter's birthday parties so they have music that is "cool" but still appropriate. Most songs are not played on the radio often so they will be a bit fresher than the often played safe songs.
It's funny that we spend ages trying to find American songs that haven't come out over here yet...Let me start by saying I'm 22, but my cousin is in 6th grade so I kind of relate. My only suggestion would be to look at UK/Australian/Swedish charts and find music popular in other countries. The girls will feel cool because they'll know the songs before they come to America and you get some fresh ideas!
What I'm loving right now:
Wings by Little Mix (seriously someone please use this song I'll love you forever)
Hall of Fame- The Script and will.i.am
Bom Bom- Sam and the Wop (not sure it would work in a routine as it doesn't have a point, but I love the beat and it would be fun for tumbling classes)
We'll be Coming Back- Calvin Harris and Example
Call my Name- Cheryl Cole
Primadonna- Marina and the Diamonds
Nights Like This- Icona Pop
Hope these help a little! I have really bizarre taste in music so if you want more europop songs let me know
