It's worth getting your kids hooked on good music instead of 'age appropriate' stuff. My boys love Intergalactic by the Beastie Boys now because of the music video. I'd much rather have Intergalactic on 8 times a day than anything cocomelon.
On that, I'd like to know your kids' reactions to the music video for Frontier Psychiatrist by The Avalanches. This is another song my boys like watching because I've forced them to watch it so many times: https://www.youtube.com/watch?v=qLrnkK2YEcE&pp=ygUVZnJvbnRpZXIgcHN5Y2hpYXRyaXN0
