How do u convert m4a files into Mp3 files HELP !!!
 

yeah so how do u convert m4a files into mp3 files , can sumone please help me.

thanks.

If you mean within Winamp, you can just use the Nullsoft Disk Writer output plug-in. If you want to do it outside of Winamp, there are many other free programs to do this, I personally use dbpoweramp but I don't think it's free anymore, I'm using an old version.

Don't use the Diskwriter, use an mp3 output plugin instead.
(And keep the m4as, lossy transcoding always causes quality loss.)
