Since it is a party, the music should be cheerful and rhythmic, which is more attractive
But it should not be too noisy. After all, it is an exhibition hall. I recommend a few songs to try
Knock Knock - lenka
Timeless - kelly clarkson
Nothing In The World - Atomic Kitten
Si Seulement - Lynnsha
C'Est Si Bon is so beautiful - Lisa Ono
I recommend adding more Lisa Ono. You can try it out in the exhibition hall and listen to it. It feels good
