Aurous has appeared, immediately drawing the wrath of the RIAA in the form of a lawsuit.
Grooveshark worked as a shell on top of Google, which basically searched the web to find the songs (most of them illegally uploaded) you wanted to hear. Aurous works the same way, but instead uses the Torrents to find illegally uploaded song files. It's similar to Popcorn Time, which does the same thing for movies and television shows and currently has those industries scrambling.
Aurous has in interface that's very similar to Spotify, and features ad-free streaming, which also means that the copyright holder, the artists and songwriters aren't getting paid. The service debuted an alpha version last week.
The music industry was quick to react, showing just how much the site is feared.
On Monday, the RIAA on behalf of UMG, Sony Music, Warner Music, Atlantic and Capitol Records, filed a lawsuit against Aurous and its creator Andrew Sampson for "willful and egregious copyright infringement."
The problem is that Aurous operates as a decentralized BitTorrent search engine, and the company can argue that it's not hosting any illegal content.
This will be an interesting legal battle that's only just beginning.
