Kids have their own generation and stuff that they are into. Don't force your kids to like what YOU like because YOU think its cool...their friends don't think YOUR old peoples music is any good LOL, Now if they really like it on their own its all good
Funny the older I get, (I'm 49yrs old) the more I feel like I'm hanging around a lot with my Dad's generation. Whenever I older dudes complaining about saggy pants, music, piercings , fads or styles etc I think to my parents complaining about the metal music, my long hair, earring, tattoo and skin tight jeans that bring the voice up a few octaves.
Styles, music and fads change from generation to generation. Older people don't understand what or why the next generation is into but the bottom line is styles, music and fads all change from generation to generation but the kids are really just the same as you and I were at that age.
Now get off my lawn and carry on.
