I'm using Winamp in it's new version. I found it friendlier
to use than the old Winamp and it is quite feature rich.

For those who experiment with a lot of players, there's
also Foobar 2000. Foobar is more frequently updated and
can play more file formats. It also has a user forum for
questions about plugins.

Foobar 2000 forum is available at Hydrogen audio.com
