Every good host knows you can't throw a party without good music, starting with crafting a great playlist. Once you have that, though, people still might have song requests, so let them be the DJ without having to keep getting on your playlist to change the song. Here are some fun ways to create a jukebox using the gadgets you may already have:

• Download the free Fluid Tunes (pictured above) for the easiest and most fun iTunes DJ — it uses your computer's camera so that all your guests need to do is gesture — literally, wave their hands — to change the song.

• If your friends have iPhones, have them download the Remote App, which lets them connect to your iTunes via your network.
• Got an Apple TV? It's a great party tool; play music from it and leave the remote on the table so everyone can pick their favorite songs.
