Lyric discussion by HurrayForSchool 

Cover art for Sidewalk lyrics by Built to Spill

I think they're encouraging people to think for themselves, instead of listening to what society tells them. "The tubes tag along" could mean that TV is always at your side, ready to spew conventional standards that society believes you should conform to. "The radar's got it wrong" says that the information we heedlessly accept as true isn't neccessarily right. What good has come from believing everything they say?

As for the sidewalk part, I'm as clueless as an anorexic sumo wrestler.
