We popped over to Belgium to check out classical music's newest concert hall.
We want to know - when did you first hear your favourite piece of music, and was it love at first sight?
Is it a piece you remember from childhood? Did you first hear it in a dramatic moment in a film? Maybe you heard it one day on Classic FM while you were driving through lovely countryside? Did the piece of music strike you immediately, or did it take time to gradually become the work you couldn't live without?
In the comments section below, tell us about when you first heard your favourite piece of music.
