Is it a sin to listen to anti-christian/anti-religious bands?

i am christian. i am kinda religious and i listen to metal. most of the bands i listen to like august burns red, etc, don't talk about religion or praise christianity. i try to only listen to christian metal bands and atheist bands are pushing it. i was wondering if it was a sin to listen to antichrist. bands and anti religion bands even if my faith wont be affected and i wont use their ideals and beliefs. and also is it a sin if i know and sing the lyrics even if i dont agree with them. i know it sounds dumb, but just like to go with the song?
