What are the bands that your parents got you into?
For me, it was the following:
Aerosmith - This is/was my parent's favorite band, so I heard a lot of it when I was growing up. It wasn't until 2002/03 that I began listening to it on my own though (and thus starting my obsession with music)
Queen - My dad had the Greatest Hits album... again it was something I heard a lot growing up. I became a diehard fan once I bought the "A Night At The Opera" and "Queen II" albums though.
Elton John - My mom got me into Elton by showing me Goodbye Yellow Brick Road
Billy Joel - I actually bought my dad a pack of 3 Billy Joel CDs for his birthday or Christmas one year. I think I listened to them more than he did, because right now the CDs are in my car.
So mainly, my parents got me started in my classic rock roots. Those 4 bands/artists above would all make my top 10.
And, while it is the opposite of the topic title, I recently got my mom into Porcupine Tree.
My dad is kind of stubborn when it comes to music and refuses to enjoy anything he didn't grow up with though.
