Patrick Carney of The Black Keys says Napster founder Sean Parker is an "a-shole", and claims his fortune was made by stealing from artists.
He was responding to Parker's recent claims at SXSW that Spotify, for which he is a board member, will make more revenue for the music industry than iTunes over the next two years.
"He's an a-shole," said Carney (via NME). "That guy has $2 billion that he made from figuring out ways to steal royalties from artists, and that's the bottom line. You can't really trust anybody like that."
However, Carney's accusation isn't quite accurate. Parker may have made his name with Napster, which kickstarted the piracy revolution, but his billions probably come from his involvement with Facebook, as portrayed by Justin Timberlake in "The Social Network".
Carney says his band isn't completely against streaming services, but they won't put all their music on until is has enough subscribers to make it financially viable. He added, "Trust me, Dan [Auerbach, Black Keys frontman] and I like to make money. If it was fair to the artist we would be involved in it.
"I honestly don't want to see Sean Parker succeed in anything. I imagine if Spotify becomes something that people are willing to pay for, then I'm sure iTunes will just create their own service, and they're actually fair to artists."
iTunes does offer its own music streaming service via iTunes Match, but it relies on the consumer already owning a copy of a song before matching it with the iTunes server for streaming. It costs $25 per year, compared to $5-10 per month for Spotify.
