Music is often the life of the party, whether it’s a dance or dinner. If you want your crowd to dance, hire a mobile DJ or become your DJ by making a playlist on a computer. A live DJ can add humor and energy to the party. Sometimes it’s fun to pass a wireless mic around and let people say whatever they want or sing along with a song. Soft music is helpful for a relaxing background soundtrack during dinner. Having a sound system at the party gives you options to make speeches.
