the most downloaded pieces of software for Windows. By the end of 1998, there were already over 60 plugins and hundreds of skins made for the software. PlayMedia filed a federal lawsuit against Nullsoft in March 1999. In May 1999, PlayMedia was granted an injunction by Federal Judge A. Howard Matz against distribution of Nitrane by Nullsoft, and the same month the lawsuit was settled out-of-court with licensing and confidentiality agreements. Soon after, Nullsoft switched to an ISO decoder from the Fraunhofer-Gesellschaft, the developers of the MP3 format. Winamp 2.10, released March 24, 1999, included a new version of the "Llama" demo.mp3 featuring a musical sting and bleating. Nullsoft was purchased by AOL in June 1999 for $80 million in stock, with Nullsoft becoming a subsidiary. AOL itself merged with Time Warner in 2000. Nullsoft relaunched the Winamp-specific winamp.com in December 1999 to provide easier access to skins, plug-ins, streaming audio, song downloads, forums, and developer resources. As of June 22, 2000, Winamp surpassed 25 million registrants. Winamp3 The next major Winamp version, Winamp3 (so spelled to include mp3 in the name and to mark its separation from the Winamp 2 codebase), was released on August 9, 2002. It was a complete rewrite of version 2, newly based on the Wasabi application framework, which offered additional functionality and flexibility. Winamp3 was developed parallel to Winamp 2, but "many users found it consumed too many system resources and was unstable (or even lacked some valued functionality, such as the ability to count or find the total duration of tracks in a playlist)". Winamp3 had no backward compatibility with Winamp 2 plugins, and the SHOUTcast sourcing plugin was not supported. No Winamp3 version of SHOUTcast was ever released. In response to users reverting to Winamp 2, Nullsoft continued the development of Winamp 2 to versions 2.9 and 2.91 in 2003, even alluding to it humorously. The beta versions 2.92 and 2.95 were released with the inclusion of some of the functionality of the upcoming Winamp 5. During this period the Wasabi cross-platform application framework and skinnable GUI toolkit was derived from parts of the Winamp3 source code. For Linux, Nullsoft released an alpha version of Winamp3 on October 9, 2001, but has not updated it despite continued user interest. During this time Winamp faced stiff competition from Apple's iTunes. Winamp 5 Winamp 5 was based on the Winamp 2 codebase, but with
