Candle Ceremony.. Please, Please Help!!

Hey.. This year at the end of september i am going to be celebrating my sweet 15.. I am going to be having a candle ceremony and im having trouble picking out a song for someone really special.. This special person isnt my boyfriend.. You can kind of say friends with benefits.. Weve been talking for quite some time now.. But i dont know what song i should put for him.. I would really appreciate it if you help me find a good song for him.. Also.. Im going to be performing a dance ( spanish dance - merengue ) but i dont know if i should do it right after the waltz and then leave with my escort to change while my court dances the waltz.. Then my escort brings me back in with different clothing and after that dance i change back into my dress or should i just stay in my dress to dance that piece? please help!
Sincerely,
Beba
