Version 1.006 was released June 7, 1997,<ref name="Wired98"/><ref name="AutoMZ-16"/> renamed "Winamp", i.e., with "amp" now in lowercase. It showed a spectrum analyzer and color-changing volume slider, but no waveform display. The AMP non-commercial license was included in its [[Online help|help menu]].

According to Tomislav Uzelac, Frankel licensed the AMP 0.7 engine June 1, 1997.<ref name="play1"/> Frankel formally founded [[Nullsoft]] Inc. in January 1998 and continued development of Winamp, which changed from freeware to $10 [[shareware]].<ref name=Wired98/> Despite the fact that there would be no extra features by paying $10, Winamp's popularity and warm reception brought Nullsoft $100,000 a month that year from $10 paper checks in the mail from paying users.<ref name="arstechnica.com" />

In March, Brian Litman, managing co-founder with Uzelac of Advanced Multimedia Products, which by then had been merged into PlayMedia Systems, sent a cease-and-desist letter to Nullsoft, claiming unlawful use of AMP.<ref>{{cite web |url=http://funkidswonderfulhistory.weebly.com/technology-inventions.html |title=Technology/ Inventions |website=British History for KidsKS2 |access-date=February 3, 2018 |archive-date=February 1, 2018 |archive-url=https://web.archive.org/web/20180201192929/http://funkidswonderfulhistory.weebly.com/technology-inventions.html |url-status=dead}}</ref> Nullsoft responded that they had replaced AMP with Nitrane,<ref name="rtd/winAMP"/> Nullsoft's proprietary decoder, but Playmedia disputed this.{{Citation needed|date=August 2011}} Third-party reviews found that Nitrane had bugs that resulted in playing back MP3s incorrectly, and that this resulted in unstable tones being added to the playback, and undoubtedly therefore violated the ISO standard. This also means that Nitrane was unlikely to have been based on the AMP software, and was more likely evidence of a hastily written MP3 decoder that didn't concern itself with standards compliance.<ref>{{cite web |url=http://mp3decoders.mp3-tech.org/decoders_winamp2_62.html |title=Winamp v2.62 mp3 decoding quality test results |website=mp3decoders.mp3-tech.org |access-date=September 29, 2019 |archive-url=https://web.archive.org/web/20171110191532/http://mp3decoders.mp3-tech.org/decoders_winamp2_62.html |archive-date=November 10, 2017 |url-status=dead}}</ref>

Version 1.90,<ref name="rtd/winAMP"/> released March 31, 1998, was the first release as a general-purpose audio player, and documented on the Winamp website as supporting plugins, of which it included two input plugins (''MOD'' and ''MP3'') and a visualization plugin.<ref name="WAv1.90"/>

The installer for Version 1.91, released 18 days later, included ''wave'', ''cdda'', and ''Windows tray handling'' plugins, as well as the famous [[Wesley Willis]]-inspired DEMO.MP3 file ''"Winamp, it really whips the llama's ass"''.<ref name="AutoMZ-17"/><ref name="RS"/> ''Mike the Llama'' is the company mascot.<ref name="rtd/winAMP"/>

By July 1998, Winamp's various versions had been downloaded over three million times.<ref name=Wired98/>
