Some people say that films or television have given them overly high expectations of people. But surely music is the ultimate example of this. It leads to expect that everyone is as torn up and soulful and expressive as the great composers, that everyone is as passionate as punk vocalists, as intense as speed metal guitarists, as joyous as the choruses of the best pop songs. The list could go on.
But surely, as I've previously stated, music is a shared experience. There's something intrinsically relatable about the music we listen to. Who's to say we aren't all as torn-up, soulful, expressive, passionate, intense, and joyous as the musicians who have set our expectations 'too high'? I'll keep believing in the average joe until he tells me not to.
On the other hand, the lower you set your expectations, the less likely you are to be disappointed. There's always that.
