Example for a dat-file:
=======================

Band: Titel
===========

  3,53 You may place text here as well :)
  4,39 Leeding blanks don't matter
  4,02
  3,48
  3,51
  4,22

Or you may leave some lines blank

  4,24
  4,16
  5,19
# 3,49 Having a '#' will make this line being ignored
$ 5,45 Having a '$' will make a song entry of the length 0.00 for this line
  4,23

But you have to have a return - that means an empty line -
at the end of the file, Sorry for that
