Cover art for A Tree for Trails lyrics by Appleseed Cast, The

sup?

i bet this song is about how a lot of stuff happens that we just sleep off, don't worry about, don't care about, etc... "this life goes lullaby out of here"- we sleep through life

"smile shows filtered sounds of fear"- after we deal with what we fear we truly experience happiness

"back into it goes through the trial you can't hear"- this could go two ways, either people don't notice how this happens, or Crisci is making this personal by saying one person he is struggling with fails to deal with their issue or something like that.

that's just my thoughts. :) tyler
