Besides the online music store integration, the update "builds in access to AOL Radio's streaming channels, an ability to find videos and other artist info without leaving the software, and a toolbar to let Firefox and other web browsers control WinAmp."
The new version is available for free in a Basic version as well as part of the Pro edition which sells for $20 USD and allows for built-in ripping of CDs to any format the user wants.
You can download WinAmp from here: WinAmp 5
