Anyways, not about that.
Your input, would you play your kids listen to lullabied Metallica, Radiohead and Nirvana?
I personally, would. I mean, no harm, right?
But some of my friends say no, because some of the songs are too "heavy-metal" [these people aren't actually my friends, random people in towns], and think that you should just play the classic version of the song.
