Ruthless subject. Not everyone will agree on the best song of all time, but there a few contenders. But here are a few that could go up for the running.
Livin' on a Prayer - Bon Jovi Bohemian Rhapsody - Queen Smells like Teen Spirit - Nirvana Losing My Religion - REM Crazy - Gnarls Barkley Hey Jude - The Beatles
I don't think any song can be singled out as the best song of all time, but Rainbow in the Dark by Dio is a nice song. I've been listening to it since I was a week old [link]
Mine would have to be 'Voice of the Soul' by Death. Just. Amazing. If you are in to rock/metal, check it out!
