Sebenernya sudah cukup lama nemu lagu unik ini di internet, lirik asli lagunya ada disini
Sekarang kita coba nyanyiin ya bareng-bareng dengan gaya Pop pake bahasa Java

class bottles
{
  public static void main(String args[])
    {
    String s = "s";
    for (int beers=99; beers>-1;)
      {
      System.out.print(beers + " bottle" + s + " of beer on the wall, ");
      System.out.println(beers + " bottle" + s + " of beer, ");
      if (beers==0)
        {
        System.out.print("Go to the store, buy some more, ");
        System.out.println("99 bottles of beer on the wall.\n");
        System.exit(0);
        }
      else
        System.out.print("Take one down, pass it around, ");
      s = (--beers == 1)?"":"s";
      System.out.println(beers + " bottle" + s + " of beer on the wall.\n");
      }
    }
}

atau, ada yang suka agak keras dikit, kita nyanyiin dengan gaya Rock ala C

#define MAXBEER (99)

void chug(int beers);

main()
{
register beers;

for(beers = MAXBEER; beers; chug(beers--))
  puts("");

puts("\nTime to buy more beer!\n");

exit(0);
}

void chug(register beers)
{
char howmany[8], *s;

s = beers != 1 ? "s" : "";
printf("%d bottle%s of beer on the wall,\n", beers, s);
printf("%d bottle%s of beeeeer . . . ,\n", beers, s);
printf("Take one down, pass it around,\n");

if(--beers) sprintf(howmany, "%d", beers); else strcpy(howmany, "No more");
s = beers != 1 ? "s" : "";
printf("%s bottle%s of beer on the wall.\n", howmany, s);
}

Bisa juga Heavy Metal lho, bahasanya Common Lisp

(in-package "CL-USER")

(defun bottle-song (&optional (in-stock 99) (stream *standard-output*))

  (format

           stream 
         "-----~2%~
          ~{~&~1&~
          ~[~^~:;~
          ~1:*~@(~

         ttle~:P o~

   (loop for bottle from in-stock downto 0 collect bottle)))
