Such a stereotypical topic. And if you don't know the artists for these songs, you're done in this thread
Cliche Greatest Rock Songs:
Stairway to Heaven
Purple Haze
Back in Black
Welcome to the Jungle
Random Stevie Ray Vaughn song
etc...
Here are a few less cliche one's that I like:
Pantera - pretty much everything they ever wrote
Guns n Roses - 'Night Train'
Velvet Revolver - 'Slither'
Rush - 'Tom Sawyer'
Tool - 'Lateralus' and 'Ticks and Leeches'
Metallica - 'One'
Alice in Chains - 'Man in the Box' and 'Again'
Zeppelin - 'Black dog', 'Houses of the Holy', or 'Immigrant Song'
Nothing says a great song can't be fairly new, which why I included some great recent songs as well
