Dubbed "Popcorn Time for music," streaming service Aurous has already had a complaint filed against it by the Recording Industry Association of America (RIAA) soon after it launched.

Although seemingly above board since it uses public APIs to search for songs on pre-existing services like SoundCloud, Spotify and YouTube – and since there is no subscription, nor any ads present – it is, despite the ambiguous legality, being raked over the coals.

The complaint alleges that Aurous "blatantly infringes the Plaintiffs’ copyrights by enabling Internet users to search for, stream, and download pirated copies of Plaintiffs’ sound recordings for immediate listening and later playback. [...] Defendants have designed their service specifically to search for and retrieve these copies from a carefully chosen set of online sources notorious for offering pirated music."

Acting on behalf of UMG, Sony Music Entertainment, Warner Bros. Records, Atlantic and Capitol Records, the RIAA further believe that amassing a user base under the flag of a pirate music streaming service is wrong, and will benefit the creators of Aurous regardless of whether or not there is any hint of monetisation.

Speaking to The Guardian, the RIAA said:

"This service is a flagrant example of a business model powered by copyright theft on a massive scale. Like Grokster, Limewire or Grooveshark, it is neither licensed nor legal. We will not allow such a service to willfully trample the rights of music creators."

And what does Aurous think of all this?

"Don't worry, we're not going anywhere, empty lawsuits aren't going to stop the innovation of the next best media player," they tweeted

"For anyone curious the @RIAA principle complaint is that we're 'profiting', anyone see any ads? We sure don’t."

In related news, the service gave up on a crowdfunding attempt recently because it "brokered some unwanted attention."
