I said pop because I guess that's the closest to describe what we like. My DH made a couple mix CDs of songs for my 15 month old, who dances to EVERYTHING that makes noise, including the dish washer and clothes dryer. But, the music we have on his CD's are Cowboy Mouth, Guster, a couple christian praise/worship-type songs, some mardi-gras type music (we live in NOLA). Basically stuff that's fun, upbeat and fun to dance around to. My daughter-in-the-womb enjoys it too, I am sure.
