Virgin records used Smashing Pumpkins as part of the Amazon-Pepsi giveaway promotion, which hasn't pleased Billy Corgan. He feels it slights his integrity:
"Recently they have ignored our pleas to give our fans special editions of our old albums, telling us they weren't interested so there is a tremendous amount of hypocrisy involved with them turning around and using us like this," Corgan said
The lawsuit asserts that Smashing Pumpkins "worked hard for over two decades" to build goodwill with fans damaged by Virgin's use of its music and image in the campaign.
Virgin could, conceivably countersue that the current Corgan-only version of the Pumpkins is doing more to ruin the band's integrity than anything they could manage.
