Best is subjective. There is no such thing as best in life, only favorites.

At least some of my favorites.

There's too many good tunes out there to name one best some of my faves in no particular order are

Freebird - Lynyrd Skynyrd

Silver Machine - Hawkwind

Ace Of Spades - Motorhead

Kick Out The Jams - MC5

Send Me Your Money - Suicidal Tendencies

Antisocial - Anthrax

White Rabbit - Jefferson Starship/Emiliana Torrini (I love both versions)

Freekers Ball - Dr Hook

Le Grange - ZZ Top

The Wall - Pink Floyd

Shine On You Crazy Diamond - Pink Floyd

Comfortably Numb - Pink Floyd

Quark Strangeness And Charm - Hawkwind

Prime Mover - Zodiac Mindwarp And The Love Reaction

Tattooed Beat Messiah - Zodiac Mindwarp And The Love Reaction

Back Seat Education - Zodiac Mindwarp And The Love Reaction

These are just a few that get a lot of play on my I-Pod but there are too many great songs to list them all (it would be easier to list bands than songs!!)

We Will Rock You. Does everything a rock song is supposed to do; get the fans screaming the words like dying cats with 80,000 other people clapping the rhythm.

Plus, Freddie Mercury is a sexy beast, so, victory by default, I guess.

"I Want To Rock & Roll" by KISS. This song is so good and motivating that it could be an anthem of Rock.
