My dad has a bunch of cool records from Hendrix, Dylan, Beatles, Bowie, Stones, Velvet Underground, Zeppelin, etc...but I don't know how much he actually listens to that stuff anymore. Thought I like all those artists, besides Dylan there's nothing I'm really really into. And he didn't get me into him. Plus my dad listens to all kinds of random stuff. Like he bought Radiohead's "Kid A" when it came out because he read a good review, but he barely listened to it and eventually I stole it. And just recently he bought the Pussycat Dolls cd, which completely perplexes me.
My mom listens to like John Mayer and stuff of that nature, I got her into some stuff on the Garden State soundtrack which I bought for her though, she likes Frou Frou, The Shins etc. And she borrowed all my Foo Fighters cds to put in her car, I guess she's pretty into them. The other day she asks me if one of the songs where Dave screams a little bit is called "Screamo" haha.
But pretty much both of my parents will listen to anything I put as long as it's pleasant, they can't take screaming/shouting.
And they'll make dumb jokes, like after I played Thursday dad was all "So that's Thursday, what does Friday sound like?" eyeroll. but I supposed all parents do that.
