Yes, my son fell in love with his first Black Eyed Peas song while watching G-Force at the theater. He jumped up and started dancing. At 3, he was pretty darn cute......moms behind me were giggling (the movie was over, the music was playing while credits were rolling). I get online and get the child friendly, censored versions of some of that stuff.
He's 4 so we play a lot of Laurie Berkner and similar music. But we play a good mix of everything (literally, everything....except tejano or polka, because they just get on my nerves). We play world beat, celtic, praise and worship, classical, specially chosen hip hop (not bad words or bad messages), rock, classic rock, oldies, funk, doo wop, ska, pop-punk, raggae, dixie, swing, country, new orleans style jazz, zydeco, OLD gospel, we listen to a lot. Music plays most of the day. We have a couple instrumental CDs (prayers/worship, some mozart adagios) as they go to bed. They are young. I do monitor content. Not so much "words" or styles, but content.
