sweden's salt has more listeners than the other salt. but ... ... who's on the main salt's pic? and who made that pic as official image? ... ... for multiple artists with the same name. i think it's unfair to make an official image ... just let the listeners decide ... ... :)
last.fm really needs to figure out multiple artists with the same name. That makes for less than pretty URLs. Who trumps who, and for what reason, in taking the 'base' URL as it were?
Regardless, the Swedish Salt has my vote. One of the best band of the 90's, and their album, Auscultate, still sounds great damn near 15 years on. Fans should check out their subsequent EP, "Delay Me Down and Make Me Wah Wah!!!"
Considering this name is shared by several bands, I don't think proposed image of whichever unknown Salt band should be up there until last.fm figures out a better way to filter different artists with the same name. As Red Apple stated, the New Orleans funk band consistently has the most plays on here.
