The iPod trick mentioned isn't geared towards the dancing portion of any event. There's more to the wedding program than just dancing. So with that being said, an iPod/iTunes/Laptop/CD player/USB Drive is very suitable to use during cocktail hour and dinner. I always get a playlist from the wedding couple of songs they'd like to hear for cocktail hour/dinner and during the dancing portion. I just let the music play off iTunes until it's time to get back on the mic or when it's time to dance. If I'm MC'ing/DJ'ing a wedding on my own, I'll record a mix of the First Dance/Father-Daughter/Mother-Son, depending on the order and flow of the program. Everything in the program is running off a playlist in iTunes and I don't start mixing until the dance floor is open.
But yes, there are those cliche songs, some cornier than others and some still work depending on the type of crowd you get. Mix the old with the new, keep the music clean and lyrically appropriate and you will be alright.
Plan, book and shop for your wedding with inspiration as your guide. Plus, save photos to your favorites!
