I was raised around classical music, and although I never got into classical music in general (I rarely listen to whole symphonies and I don't spend much of my music time listening to classical music), I loved playing some classical songs as a child. Playing the music gave me positive feelings about the genre.
Three of the songs that got me into classical are these:
Johannes Brahms - Waltz
I played a simpler version of this very pretty song on my violin when I was a child. I still enjoy listening to this more complicated version:
