Just a few days after the Motion Picture Association of America (MPAA) filed a lawsuit against Megaupload, the Recording Industry Association of America (RIAA) yesterday filed a similar lawsuit against the now defunct website and its founder Kim Dotcom. Both were filed at the U.S. District Court in Alexandria, Virginia.

The lawsuit, which was filed on behalf of record companies like Warner Music, UMG Recordings, Sony Music, and Capitol Records, accuses the file sharing website of "massive copyright infringement" of music, and includes as evidence a list of 87 songs by artists such as Lady Gaga, Jay Z, and Pink, that the association said it found on the website.

In addition to Kim Dotcom, the lawsuit also targets the website's co-founder and CTO Mathias Ortmann, and head programmer Bram van der Kolk.

Megaupload was a popular file sharing website that hosted any kind of content its users wanted to share. It was a smooth ride until 2011, when the office of the U.S. Trade Representative (USTR) added the service to its list of “notorious markets” for copyrighted material, resulting in a federal lawsuit.

Responding to the development, Ira Rothken, member of Dotcom's legal team said that the case was an assault on cloud storage. "RIAA, MPAA, and DOJ are like three blind mice following each other in the pursuit of meritless [copyright] claims and assault on [copyright] neutral cloud tech", he tweeted.
