M4A format? what plays this

I just got a nice disc but it's all in m4a format and i cant play it on Itunes or Windows MP.

does anyone know a program that will convert these files to Mp3?

thanks

Thats like a fifty dollar bill. Nero should do it. Fucking itunes

M4A files are higher quality and usually smaller than mp3 files, however unlike mp3, no licenses are required to play it..

Winamp Media Player - MP3 Player, Multimedia Player, MP3 Music, Skins, Plug-ins should open em.
