I am so lucky because I have three guys who are complete music freaks. We are very selective about the music we listen to in our household. We told our boys from very early on that no matter what style of music they wanted to listen to we would let them listen to that style, but we would have to find a group that had lyrics that we approved of for them.
Big Guy and Little Guy both showed a love for rock music very early. Neither of them cared very music for "kid" music or nursery rhymes. They loved what they called "good" music. When they were little and could earn rewards we would give them a new CD as one of their options and they would always pick the CD as their reward.
One group that is ALL of our favorites is THIRD DAY! We literally have every one of their CD's. If their song comes on the radio, everybody screams, "Turn it up!!"
It is really hard to narrow down to just one of our favorites, but this is a favorite of mine:
If you have a niece, nephew, husband, son, daughter, brother-in-law... anyone who loves music and you want to buy them some awesome music for Christmas... I highly recommend ANYTHING by Third Day!
