This is an interesting topic. Thing is, is the answer the most successful band of the decade? Most influential? Best quality of music?
I liken the Strokes to the NY Dolls. They made an enormous splash on their arrival, based just as much on their image as their songs. They made a big impact on subsequent popular music, in the U.S. and abroad, and became music-culture icons. That, however, did not translate into correspondingly large sales, which they haven't enjoyed, and their subsequent releases have been whimpers.
