#imagine you have a song stuck in your head. worse, you have #only a few lines from a song stuck in your head. they just #keep repeating over and over. the specific lines you have #stuck in your head are stored in the variable lyrics. # #you can only stay sane so long while doing this. #specifically, you can only listen to lines_of_sanity lines #before going crazy. once you've reached lines_of_sanity, #your brain will finish out the current list, then crumble.
