Music is a universal language, where the meaning cannot be lost in translation. If I say something in English to someone German, he may not understand exactly what I mean, but if I play an emotional tune on an instrument, it doesn't matter if I speak in English, German, French or even some african guy. They'll still be able to understand what I'm trying to convey.

Aside from that, it's also great entertainment. And as I realized earlier today while eating breakfast: Life without music is like Strawberry Jam without pieces of Strawberry. It's just not as good.
