2005 Poll says Pearl Jam #1 Aerosmith comes in #2.
Since then Pearl Jam put out their best studio album in 10 years. They are definitely on my list as well. CCR and the Beach Boys I can't argue with. GNR would make my list. Then I have trouble deciding between the Doors and Aerosmith to round out the 5.
No particular order
CCR
Beach Boys
GNR
Pearl Jam
The Doors
