I have a rule that my teenage daughters are not allowed to download any songs from the Internet to play on their iPods until I’ve given my approval. Do you know what I call the wires that come out of an iPod and connect onto the small earphones that go into a teenager’s ears? Pipelines. Here’s what travels through those pipelines: (1) sewage that is pumped directly into our children’s brains (and imaginations) that will eventually corrupt the way they think and behave; or (2) meaningful music that can help our children to ponder and appreciate some of the beautiful things in life.
