Classical music at all occasions

I get a lot of junk mail, but yesterday's was nearly the best ever. Música CLÁSICA para toda ocasión arrived at my door. A free CD of "Classical music for all occassions" and an offer to receive a welcome packet with over a $45.00 value! And in Spanish too! What I want to know is how did they find out I speak Spanish? And who told them I like classical music at all occasions?
