anyone give advise on what music is best for this event?

any current chart stuff -

madonna - hung up
black eyed peas - my humps

the odd party dance - macarena, saturday night, cha cha slide, oops upside your head etc.

also

gwen stefani
charlotte church
sean paul

that's what the 14 year olds wanted at my last gig

they will ask requests anyway - in my experience they do

i do a kids disco for 7- 13 year olds once a month and its usually chart stuff, alot of akon lonely,belly dance,50 cent, the odd party tune normally cha cha slide so kids these days are more into chart stuff at an early age now
