Frontwoman Amy Lee has filed a lawsuit against Evanescene's record label, Wind-Up Records, claiming the company has improperly pocketed a large portion of the group's royalties.

TMZ.com reports the singer’s lawsuit claims the record company shorted the band a total of $1.5 million earned from their music. In addition, Lee alleges the label launched a campaign to sabotage Evanescence by “replacing its promoters with a bunch of idiots” who constantly provided them with “lame ideas.”

Wind-Up Records has yet to release a statement on the issue.
