ok ppl, i dont want to hear any Beatles because it would be an unfair fight and i want atleast a top 3 with a reason why you you think it is the best song. oh ant dont forget to write the artist

my top 3:

1- Enter sandman-metallica-metallica(black): for its guitar intro and awesome video
2- Welcome to the jungle-GNR-Appetite for destruction:because it is number 1 on vh1.com so 3m ppl cannot be wrong
3- Given up- LP -minutes to midnight just because i reaaaaaly like that song

sorry ppl in cant type

Wow! Quite a debatable question there Rock
There are millions of greatest songs out there & even my favorite could have been slightly better

But then again if you put a water pistol to my head...I would choose :

Eagles - Hotel California
This song is probably the greatest rock song ever written (for me that is) The lyrics are dark and almost dreamy, something quite sexual about it too. The guitar starts acoustic & slowly becomes electric 3/4 of the way through - sends shivers up & down my body every time CLASSIC

Judas Priest - Victim of Changes
Listen to the guitar riff. 1976 this song was recorded & if it were to be released today it would still be just as powerful. Rob Halford screaming after each riff sounds fantastic.

KISS - Love Gun
A very upbeat happy, aggressive song full of lust, probably shocked everyone back in the day .Again the guitar riff is fast and catchy with the lyrics being sreamed at the victim on the other side :]

There are millions more you know...

I have to say that I LOVE def leppard "pour some sugar on me"

"You Know You're Right" by Nirvana
"Adam's Song" by Blink-182
"Hitchin' a Ride" by Green Day

I agree with all of them
