When you form a column with every line (in the order they appear), you get a square of 32 by 16 digits. If you consider each successive pair of digits as one number, the square is made up of 16 by 16 numbers. Delete each '00' out of those pairs, and you get the same configuration as the crosswords Freddy posted on Imgur (

The longest word (horizontal, on the first line) is 13 letters long. The numbers corresponding to those squares are:
77 47
40 32 82
53 99 12
40 58
68 68 53The italicized, underlined and bolded numbers are repeated. Since "Misunderstood" is 13 letters long, and the repeated letters occupy the same places as the repeated numbers, you can fit that word on that line of 13 squares.
You can continue to look for patterns, or simply start replacing numbers with letters until you fill in all squares. The crossword ends up consisting entirely of words from DT's song-titles. (There's even "Raw".

)
Joining the 15 blue squares, you get
IWalkBesideYou, plus and extra 'B'. The latter is either part of the password, or just a cool nugget (since most of "I Walk Beside You" is in the key of Bm)
The next step is to understand the meaning or use of the 10 squares which include a small symbol on their upper-left corner. Those symbols are:
- "1" (letter: B)
- "2" (letter: I)
- "3" (letter: T)
- "4" (letter: L)
- "5"
- "6"
- "7(small)" (letter: V)

- "X1-(!)" (letter: D)
- "x2(small)" (letter: S)
It's hard to determine which is the square with the "5", the "6" and the remaining symbol. In any event, those are:
- the blue square with the U from "Misunderstood",
- the left-most square in the third line (letter: F), and
- the red-ish, eighth square in the third line (letter: B).
