top 20 songs of all time

[CRAZY-HORSE]

i have been pondering this question for a few months now.
i have written lists, then re-written them over and over again and now i am fairly satisfied with the list i have come up with.

so over the next 20 days i will post, in no particular order, what i consider to be 20 of the greatest songs of all time.

my list contains two artists/songwriters with multiple entries (one has 2 and the other has 3 entries).
there is one instrumental on the list also.
                                                                          1930                                                              1986.
the oldest song on my list was originally released in 1955 and the most recent addition comes from 1977.

so before i start are there any guesses on:

1: the two artists who have multiple entries
2: the oldest song on the list
3: the most recent song on the list
4: what the instrumental track is


i will start the list on Monday 17th April to give you all a chance to think about your guesses.

see the 7th post in the thread for further date info before answering.
