I grew up listening to a lot of the same music my parents listened to when they were my age. So basically oldies, classic rock, singers/standards.....that sort of thing. For my birthday one year, my dad took me to a real record store (not CDs....vinyl!) and said I could pick out an album for myself. I bought Led Zeppelin's Physical Graffiti because I liked the song Kashmir and it was on it. After that, I listened to as much of their music as I could and whenever I had the chance, I would buy either their CDs or their albums.
I was probably 13 or 14 at the time, I think.
