If there was nothing deep about them, you wouldn't need to read the lyrics more than once to even get a clue what Maynard is writing about.
Example: 46 & 2 is a song written about human DNA and chromosomes.
The shadow line of the song is a reference to a darker part of the mind, that no one likes to admit they have. 46 & 2 refers to the next level of human awareness, as the song itself reflects the band's intrest in the theories of Drunvalo Melchizadek. Too technical for me to go into details with.
Now this isn't one example of them being more than your ordinary band?
