Popular YouTube user Michelle Phan is being sued for alleged copyright infringement on songs she has used in her videos, according to reports from the BBC. Ultra Records claims that Phan has used 50 of its songs in her YouTube posts and on her website illegally despite one of the label's own artists objecting to the legal action.

Phan's YouTube channel centers around using and buying makeup, and her videos are often backed by upbeat music with the artist credited in the video's description. Artists whom Phan has used in her videos include Kaskade, deadmau5, and Calvin Harris.

Kaskade spoke out on Twitter about the lawsuit, condemning Ultra for pursuing Phan for copyright infringement. "Copyright law is a dinosaur, ill-suited for the landscape of today’s media," he wrote. "We can’t love (& won’t buy) music we haven’t heard." If it's exposure artists are looking for, Phan's audience isn't a bad target. She boasts more than six million subscribers and videos that consistently crack a million views each.

A spokesman for Phan told the BBC that Ultra "agreed to allow Michelle to use the music and Michelle intends to fight this lawsuit." Ultra Records is seeking $150,000 from Phan for each instance of infringement.
