Over the years, many musicians have spoken out against Spotify.
Many have denounced the fact that their music is available for free, but they earn very little from streaming - unless you're the Ed Sheerans and Taylor Swifts of the music world.
Now, however, the publishing company behind one major artist has taken a stand by bringing a lawsuit against the streaming giant - although reports suggest that he himself was not even aware that it was being filed.
Eminem's publisher Eight Mile Style is suing Spotify for deliberate copyright infringement of approximately 250 of his songs that are available on Spotify.
It follows on from a similar $1.6 billion lawsuit brought by publishers Wixen last year.
They claim that Spotify does not have a licence to stream those songs, and despite doing so billions of times, "Spotify has not accounted to Eight Mile or paid Eight Mile for these streams but instead remitted random payments of some sort, which only purport to account for a fraction of those streams."
The suit also claims that Spotify have attempted to exploit a loophole by placing the song 'Lose Yourself' in a category called 'Copyright Control', reserved for songs whose owners are not known. It also attacks new legislation that was brought in last year to allegedly protect songwriters and publishers, the Music Modernization Act, and says that Spotify has not fulfilled its obligations under the new law.
It goes without saying that if this suit was somehow successful, both the potential sum awarded (up to $120 million for unpaid royalties, allegedly) and the impact it would have on the music industry would be huge.
