There are lots of media players for Windows x86 / 64 systems. In this document, I plan on focusing on two. These are WinAmp and Songbird. Winamp is probably still the best MP3 / WAV / OGG player out there, though it is not open-source. It is free, however. Winamp is what I use to stream crazyskills radio. Songbird is a different beast altogether. Songbird is much more like iTunes, in that it can even synch with an iPod. Songbird is lightweight and open source. Songbird is an excellent replacement for iTunes.
WinAmp is available in a great number of languages. The latest English version (5.55) for the Windows x86 / 64 OS is available here [winamp.com].
Songbird is available in a great number of languages. The latest English version (1.0.0) for the Windows x86 / 64 OS is available here [getsongbird.com].
