Aw, man. There are some really good ones, but to ask about my favorite songs for the road is like asking for my favorite songs in general

So(sighing heavily) in no particular order...

1)Velocity Girl: Go Costal(Recommended for roads like Ocean Parkway on Long Island, I-95 in Georgia, or the Chesapeake Bay Bridge & Tunnel).
2)Foo Fighters: Alone + Easy Target.
3)Rancid Polecats: Peterbilt.
4)Go-Go's: Speeding.
5)Rush: Dreamline(I agree with 58_Roadmaster).
6)Living Colour: Crosstown Traffic(Yes, the Jimi Hendrix cover).
7)America: Ventura Highway.
8)Sammy Hagar: I Can't Drive 55.
9)Motley Crue: Kickstart My Heart.
10)Arggh! Too many to choose from!

Great topic! with parents or friends we (or usually I, as on my Ipod) usually listen to:

Aerosmith: Walk this Way
Twisted Sister: I wanna Rock
Nirvana: In Bloom
Van Halen: Jump
Led Zepplien: Stairway to Heaven
Jimmi Hendrix: Purple Haze
The Offspring: Pretty Fly (for a white guy)
Warrant: Cherry Pie
Feeder: Buck Rodgers
Guns n' Roses: Paradise City.

Also, the greatest ever driving song; 'Radar Love'! Including Bon Jovi, Smashing Pumpkins, Ozzy Osbourne and Eric Clapton etc.

JBMX4C, I am the same way. The best song for a freeway onramp is, of course, "About To Crash (Reprise)."
For those who don't know this amazing band, here is a live recording:

.for cross country or daily driving i pretty much just crank up dream theater.i mean 1 DT song of 20 minutes can get me to work.

1. Linkin Park - Enth E ND
2. T.I. - Ride Wit Me
3. Lexicon - Rock to the Rythmn
4. Daft Punk - Human After All
5. Lil Jon and The East Side Boyz - Get Low
6. The Crystal Method - I Know It's You
7. The Crystal Method - Vapor Trail
8. Daft Punk - Technologic
9. Distrubed - This Moment
10. Smashing Pumpkins - Doomsday Clock

But really it's just anything off The Transformers Soundtrack, Crystal Method's Leigon of Boom, or Daft Punk's Human After All albums.

I could talk about this topic forever...

Mmmm, good topic! There are quite a few songs that are better to listen to in the car than in other situations. The passing motion of all the things around you kind of serves as a real-life music video of sorts

Some of the ones I like, mostly classic rock since I especially like listening to the aucoustics while driving:

"Runnin Down a Dream" - Tom Petty

"Two Tickets to Paradise" -Eddie Money

"Free Bird" - Lynyard Skinner

"Hold the Line" - Toto

"White Wedding" - Billy Idol

"Eminence Front" - The Who

"Viva la Vida" - Coldplay

And now that I think of it "Clocks" would be a good song for the car listening Neptune, I'll have to do that sometime

Mine: (listed in no particular order)

1: "December" - by - Collective Soul

2: "Clocks" - by - Coldplay

3: "Burning Bright" -by - Shinedown

4: "Learning to Fly" - by - Heartbreakers (Tom Petty)

5: "Take the Money and Run" - by - Steve Miller Band

6: "Everyday Is a Winding Road" - by - Sheryl Crow

7: "Bittersweet Symphony" - by - The Verve (I like to listen to this while driving the Expedition through the mountains)

8: "She Sells Sanctuary" - by - The Cult

9: "Back In Back" - by - AC/DC

10: "Dreams" - by - The Cranberries
