It's TOTALLY fine to have a wide mixture of genres for the reception music. Most people will do this.
My man and I have an extremely wide range of music that we like. We're playing everything from contemporary christian to rap, from old country to rock and roll.
We're renting our own music equipment, so we're in charge of organizing all the music. We loaded up our iPod specifically for the wedding reception. Hundreds of songs, and many, many minutes of downloading!
Here's a tiny sample of what our list consists of:
Beyonce - Crazy in Love
Bob Marley - Red Red Wine
Bob Seger - Old Time Rock and Roll
George Thourogood - One Bourbon, One Scotch, One Beer
Gwen Stefani - Hollaback Girl
Jamiroquai - Little L
Kid Rock - All Summer Long
Lady Gaga - Poker Face
Lynark Skynyrd - Sweet Home Alabama
Nitty Gritty Dirt Band - Cadillac Ranch
R. Kelly - Ignition
Ram Jam - Black Betty
Run DMC - It's Tricky
Sweet - Little Willy
The Rolling Stones - Brown Suger
Tom Jones - Sex Bomb
Wild Cherry - Play That Funky Music
We've got TONS more on top of this. My dad loves the oldies, so we made sure to include a ton of that, and my husband really likes rap so we've even got some Tu Pac in there.
You definetly WANT to have a mix of types of music for a reception. Helps keep everyone happy!
