The music for your special day is something (in my own experience) should be sorted out before you arrive!
But many of us travel with so many devices I am sure that we can find something.
(But make sure the device is compatible with the system to where you are going)
Nothing will help me forget when the guest chose Titanic for her entrance song - that is their choice - BUT the Instrumental version came on!!!!!
I usually ask for three;
1) The bride arrive
2) The bride and groom depart married
3) The first dance
But it is your day - what's wrong with a bit of fun :)
