Thanks bennyboyamo for posting this in our Back page News on the forums.
Winamp is a fast media player for Windows, not only does it play MP3 but a range of other formats including video. Version 5 features the best that Winamp v2 and v3 had to offer and I must say, it made me go back :)
This one isn"t on the "official" site yet, but you can grab it here in both flavors, Lite and Full.. Like most software these days, registering it will get you more advanced options like Unrestricted CD Burning, MP3 Encoding and Unrestricted CD Ripping.
