I have downloaded WinAMP 2.24 & the speex codec so you can quickly install them, and listen to No Agenda!
Be sure to *NOT* install the Windows Media pluggin, as it will not work on modern versions of Windows, while this version of WinAMP will work on Windows 7.
WinAMP 2.24 - 1.2MB
Speex codec for WinAMP - 116k
Wininet - for machines without Internet Explorer 3.0 or higher
