My mom doesnt like a lot of music I listen to, and I think a lot of it is pretty toned down and good, she absolutely hates things with lots of swears like Mindless Self Indulgence, but I just dont listen to it when shes around.
You should look at it this way, they grew up listening to COMPLETELY different music, and oftentimes people dont like things out of their own norm or what they have established as what they like. I dont like my moms 70s and 80s music, she doesnt like my 00s music. Its kinda like your friends, are you really all that concerned with whether you like their music and you like theirs? Everyone has different likes, oh well, respect it, move on, and dont disrespect them by playing things they absolutely hate.
